Shale Shaker-Basket Mechanism

The shale shaker basket should be capable of adjusting its angle to accommodate numerous flow rates of drilling fluids in the solids control system and to maximise the utilization of the shaker bed, this can be wherever the fishing mechanism plays a vital half.
The lubricant flowing over the shaker bed is selected into 2 categories:
Pool: that is that the space of the screening deck that consists principally of lubricant with trained cuttings suspended inside it.
Beach: is that the space wherever the fluid has been principally faraway from the cuttings and that they begin to appear sort of a pile of solids.

As a rule of thumb the Beach and pool area unit maintained at a quantitative relation of eightieth pool and two hundredth beach, this in fact will modification reckoning on the necessities of cutting waterlessness and flow rates.

The mechanism plays an important role in solids control.
There area unit numerous fishing mechanisms presently in use that vary from hydraulic to gas and mechanical, they will be controlled from either one facet of the shaker or should be adjusted one by one per facet. Mechanical fishing mechanisms usually will be terribly dependable often requiring less maintenance however typically take longer to control than their hydraulic or gas counterparts wherever because the hydraulic/pneumatic fishing mechanisms area unit a lot of quicker to control and need less a physical means that of operation.


Brightway Shaker deck angle adjustment:
There are lifter, pipe, lifter pipe, scale indicator, scale, connection plate, etc. When we make adjustment, handle wheel rotary by clockwise, shaker deck angle will be larger; handle wheel rotary by anti clockwise shaker deck angle will be less.
Shale shaker output angle adjustment can be operated under running and off. When finish the shaker deliver it, the shaker deck is 0°. When user operate shaker, according to drilling mud property and flow rate on job site, and adopts same shaker screen, the angle is higher, the treating performance will be better while treating capacity will be higher. When drilling fluid is leaking on shaker deck, increase deck angle can get rid of fluid flow away.
Angle is 0~ +5°

HOW JET MUD MIXER WORKS

The JET MUD MIXER is used to make up drilling fluid or increase total amount of the drilling fluid, change the fluid density, viscosity, and dehydration. When making up again, put the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) into the recycle tank through the jet unit. If put them directly, the materials of drilling fluid and chemical additives will be deposited largely or dump together and we can’t obtain diffused and well-proportioned drilling fluid.

BWSLH jet mixing device is a unit used together with the solid control system for petroleum drilling. It is suitable for drilling from 1,500 meters to 6,000 meters and can strengthen and make up drilling fluid through the fixed control system horizontally. The unit includes one sand pump, one jet mixing funnel and one jet mixer that are installed in a base with pipe valves. It is safe and stable and can be moved conveniently.

Installation and Application

1. Installation

(1) According to the on-site situation, the tank should be at the same level as the slurry tank.

(2) Connect the suction inlet of the pump to the tank body with hoses.

(3) At the outlet, connect the jet mixing to the inlet of the tank with creeping pipe.

(4) Switch on the power, and see if the rotation direction of the sand pump is right.

2. Application

(1) For operation and maintenance of the sand pump, see its operation and maintenance instructions.

(2) BWSLH jet mixing device is shown as the figure.

(3) Before use, open the inlet butterfly valve of the sand pump. Then start the sand pump. When the sand pump runs normally, open the inlet butterfly valve of the funnel, then add the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) from the funnel to strengthen and make up the slurry.

(4) Before stop the pump, close the inlet butterfly valve  of the funnel to prevent the instant pressure decrease, which resulting in overflowing of slurry from the surface of the funnel.

(5) In winter, when BWSLH jet mixing device stops working for a long time, close the suction inlet butterfly valve 1, then loosen the pipe plugs under the casing of the sand pump and ones under the inlet pipe of the funnel to drain the slurry to prevent the pump body and pipeline from being blocked and frost cracked.

Comparison Between Brandt Mud Agitator and Brightway Mud Agitator

Let's have a comparison between Brandt mud agitator and Brightway mud agitator.

HIGH QUALITY AND TIME-PROVEN MECHANICAL AGITATION
Agitators serve the drilling industry with high quality and time-proven mechanical agitation.
VMA
The VMA agitator is vertically mounted, reducing the footprint requirement. It offers a motor with a vertical direct mount to a helical inline gearbox with a drop bearing configuration.
Impellers
Impellers are available with flat blades (radial flow), contour blades (axial flow) and canted blades (radial/axial flow). The impellers are sized according to tank volume and expected duty. Active mud system compartments - such as solids removal sections, mud mixing sections and slug pits - which need a higher shear force to produce immediate mixing, are another consideration in impeller sizing.
Shafts
Several types of shafts are offered.Mild steel shafts are cut to length and joined to the gearbox output shaft with a rigid coupling. Solid shafts are keyed at the bottom for adjustment of impeller height. Hollow pipe shafts are available for deep tanks. They are supplied in flanged sections and bolted together making them ideal when lifting height is limited.

Brightway oilfield mud agitator features a “C” face motor couple to a rugged oilfield gearbox, which eliminates misalignment and troublesome couplings. This configuration promotes long motor and gearbox bearing life. Mud Agitator is used in mud systems to suspend solids and maintain homogeneous mixture throughout the system.

Mud Agitator Features and Benefits

1. Structure: Small footprint and compact structure

2. Reduction gearbox: Helical-bevel design or worm design according to customer requirement

3. Motor: Explosion-proof electrical motor, and can be the style of horizontal or vertical

HOW MUD CLEANER WORKS?

Desanders are used to separate sand which is mixed with drilling muds. During drilling process mud is being poured as excavation is getting deeper, this mud also mixes with soil, thus being contaminated with sand and silt, in such a way, that when excavation is finished, it is necessary to recycle mud in order to separate sand from mud and get a clean mud that will be used in next excavations. Each country establishes its own regulations on maximum allowed sand content in drilling mud before concreting operation is carried out, in order to prevent concrete contamination with sand and soil, and Desanders are used for this purpose.

A desilter is used to separate silts from drilling muds. The cut point can be as low as 7-10 μm. As muds are being used in drilling operations, they are contaminated with silts. In order to use again these muds, it is necessary to separate silts and also to recycle muds to dispose them at the end of work duty.

Mud cleaner is the combination of desander and desilter.

Brightway offers a line of mud cleaners that employs a two-stage separation process for the ultimate in drilling fluid recovery. Our mud cleaners use a combination of hydrocyclones mounted over a shale shaker to operate as a single unit. 

Brightway mud cleaners are designed to handle the entire circulating volume to remove and dry solids while retaining premium base fluid. They are equally effective for both weighted and unweighted drilling-fluids.

With our mud cleaners, the hydrocyclones make the primary separation with underflow directed onto the shaker vibrating screen. Brightway mud cleaners have been proved effective in lowering both drilling-fluid and disposal costs.

MUD GAS SEPARATOR

Mud Gas Separator is commonly called a gas-buster or poor boy degasser. It captures and separates large volume of free gas within the drilling fluid. If there is a "KICK" situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates. The gas then is forced to flow through a line and vent it to a flare. A "KICK" situation happens when the annular hydrostatic pressure in a drilling well temporarily (and usually relatively suddenly) falls below that of the formation, or pore, pressure in a permeable section downhole, and before control of the situation is lost.
It is always safe to design the mud/gas separator that will handle the maximum possible gas flow that can occur.

The principle of mud/gas separation for different types of vessels is the same.
• Closed bottom type
• Open bottom type
• Float type

The closed-bottom separator, as the name implies, is closed at the vessel bottom with the mud return line directed back to the mud tanks. Commonly called the poor boy, the open-bottom mud gas separator is typically mounted on a mud tank or trip tank with the bottom of the separator body submerged in the mud. Fluid level (mud leg) is maintained in a float-type mud gas separator by a float/valve configuration. The float opens and closes a valve on the mud return line to maintain the mud-leg level. According to pedestal or base type there are
• Fixed type
• Elevating type
Poor boy degasser in China is usually named according to vessel diameter.
Brightway have the below models for mud gas separator.
• ZYQ800
• ZYQ1000
• ZYQ1200

What is Solids Control System?

Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally solid control system is consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as high efficient mud cleaner. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of the mud tank. After separating the solids, the clean mud would be pumped into the borehole again.

Drilling fluid maintenance cost, clean up, and disposal cost as well as the overall cost of boring can be reduced dramatically when proper solids control techniques are utilized. These facts were recognized in the oil industry in the late 19th century when open earthen pits were used to separate the cuttings from the borehole. This was accomplished by a series of weirs and settling pits that allowed the solids to naturally settle out by using gravity. The clean mud then flowed into a suction pit to be re-pumped down the hole. This was the first solids control technique ever used.

The next innovation in solids control came when the shale shaker was introduced in the early 1930s for the oil industry. The shale shakers were derived from technology used in the mining industry. The shale shaker remains today the primary piece of solids control equipment utilized in the industry.
Another machine borrowed from the mining industry in the 1930s was the cone classifier or hydrocyclone. The basic principle of this device involves the centripetal forces brought about by the high velocity of the drilling fluid spinning in the cone, forcing the larger and heavier solids to settle outward toward the cyclone wall and downward toward the underflow solids discharge. Together with the shale shaker, hydrocyclones have become an integral part of today’s solid control system. In an addition to shakers and hydrocyclones, the use of a high-speed centrifuge has significantly contributed to the ability of a drilling operation to reduce the amount of mud to be built and diesel/barite additions to maintain optimum low and high gravity solids proportions.
Recent advances in solids control include the creation of a closed loop system which allows for increased environmental control and reduction in the potential for spills of drilling fluids. Several US states have either passed or are considering the implementation of closed loop systems, particularly for hydro-fracturing operations.
The most famous solids control system manufactuer are almost from US, the top 3 are: Derrick Equipment Company, MI Swaco Solids Control Company and NOV Brandt Solids Control Company.
Brighway is also competitive in the market because of the efficiency of the machine and the competitive price.

Equipment:
Fluids processing system
Shale shaker The shale shaker is the first stage of solids control equipment in the fluids processing system,which removes cuttings with diameter above 75μm from the drilling fluids brought up from the wells.Afterwards,the treated fluids flow into the tank waiting to be processed again in the next stage of the system.
Desander Desander is the second stage of solids control equipment.It is mainly used to take away the solids with diameter ranging from 45 to 74 μm from the formerly treated fluids and then send them to the next stage for more purification.
Desilter Desilter is the third stage of solids control equipment.In this case,the solids with diameter ranging from 15 to 44 μm are to be separated from the rest,which will go through further processing.

Mud Gun

Mud Gun is used in a solids control system. It is a tool which is mainly used for mixing drilling mud in the circulatory system and to prevent the mud from precipitating. The structure of equipment is simple offering flexible operation and easy use. A mud gun is commonly used to guard against settling in a solids control system. The mud gun is normally installed in a mud tank.

Furthermore, it is usually used together with mud agitator. The mud agitator is used in the middle of the tank while the mud gun is placed in the corner of the tank.

Horizontal Spiral Centrifuge

The working principle of horizontal spiral centrifuge and workflow
Horizontal spiral centrifuge is separated by centrifugal sedimentation principle extruded suspension to achieve solid-liquid separation equipment. Drum is a cylindrical - conical composite cylinder, both ends bearing on the base , so that the motor pulley driven through high-speed rotation . Helices with spiral blade rotor , supported by bearings at both ends of the drum , the drum rotation passing through the differential to the spiral , because the differential differential role in making the screw speed slower than 1% of the drum speed to 3% , so that the drum and the screw there is a relative movement of the screw conveyor structure constituted . The suspension to be separated to the feed tube through the transfer tube spiral added , the acceleration of the disc by the cloth feed holes are thrown into the drum , this, the suspension is placed in a strong centrifugal force field , the solid phase large mass volume , suffered a large centrifugal force , so that the deposition on the inner wall of the drum , brought out from the screw conveyor to the small discharge port , where the centrifugal force to sediment thrown into the enclosure interior . Be clarified liquid phase through to the big end of the spiral channel flow. Overflows through the overflow hole into the cabinet through the exhaust conduit . Thus, the solid-liquid two -phase suspension be separated .

The test results in the case of an oil field trials by the graph above , the separation of the machine operation is continuous and automatic, so horizontal spiral centrifuge separation effect and ease of operation are superior plate and frame pressure filter machine and filter belt filter press , is currently more advanced solid-liquid separation device .

Compact Drilling fluids System for HDD

Always compact drilling fluids system is welcome for horizontal directional drilling(HDD).
Compact represents cost saving in transportation&labor, easy for maintenance,smaller footprint, etc.

I am very interested in the different compact drilling fluids system designs in market. I respect our competitor and in some aspect, their good work helps us to think and grow.

Have a look at the below Triflo compact HDD system 100GPM-150GPM

Compact HDD System 100GPM-150GPM

1x shale shaker

1xmud cleaner (4x4" desilter+bottom shaler shaker)

1x mud hopper

3x pump-2x3 centrifuge pump 5.5kw

( one for desilter, one for mud mixing, the last one for pumping the mud from the tank back to the drilling)

1xtank overall size: 1.5x5.4x1.8m, tank size:1.5x2.7x1.8m

Advantage:

• Small footprint
• In the 3 pumps, including the pump to have the mud back to the drilling use
• 2 stage of separating: shale shaker-mud cleaner with desilter

Disadvantage: 

• The tank body without the folds decrease the loading strength.

Taking our tank body panel as below for example, the folds on the body can avoid the shape transformation, then strengthen the load ability.

Brightway Mud Tank

• 3x2 centrifugal pump, 5.5kw, from my knowledge, such pump flow is about 20 m3/h, about 88GPM, I wonder if it can meet the requirement of the 4x 4" desilters?

• Such compact HDD system, I can not see the walkways and guardrail.

• From the aspect of separating stages, it is without the desander stage.

In general, this Triflo system is the compact one and only the end user can tell the final treatment effect is good or not.

The above is only my thoughts from my understanding read from the picture.

How we Brightway design the compact HDD system?

We want to do the 2 in 1 mud system or 3 in 1 system including the 3 separation stages of shale shaker, desander and desilter and the mud mixing hopper, with the size as 5.5x2.3x1.8m, Volume about 10 m3, capacity about 250GPM.

How Mud Gas Separator/ Poor Boy Degasser Work?

Mud gas separator, also named as poor boy degasser, how does it separate the gas from the drilling mud?


The below drawing can explain the mud flow.

There are 4 colors (blue/green/red/brown) of arrows in the drawing, which present mud, gas, liquid of mud and mud deposit.

mud gas separator

• The mud from the drilling well goes into the poor boy degasser as showed in the blue arrow. Because of the gravity, the mud drops down at the inner structure of poor boy degasser. 

• With the gas bubbles bursting out, the gas flows with the routine of the green arrow. If to burn the harmful gas, connect gas exist of poor boy digasser to flare ignition device by pipe  in about 30 meters away from the poor boy degasser.

• The mud liquid flows out as the red arrow showed, and this mud liquid can go to the drilling fluids recycling equipment such as shale shaker, mud cleaner, centrifuge, etc for further separation. 

• If to clean the mud deposit accumulated in the poor boy degasser, the bottom hole is to drain the mud solids out as specified in the brown arrow. 

• The safety valve on the top is to release the gas in case the inner pressure is very big, and the pressure meter on the top is to read the inner pressure.

Brigthway liquid gas separator are sold at home and abroad.

How hydracyclone works?

Hydrocyclones (also referred to as cyclones or cones) are simple mechanical devices, without moving parts, designed to speed up the settling process. Feed energy is transformed into centrifugal force inside the cyclone to accelerate particle settling in accordance with Stoke’s Law. In essence, a cyclone is a miniature settling pit which allows very rapid settling of solids under controlled conditions.

Hydrocyclones are important in solids control systems because of their ability to efficiently remove particles smaller than the finest mesh screens. They are also uncomplicated devices, which make them easy to use and maintain.



Hydracyclone

A hydrocyclone consists of a cylindrical/conical shell with a small opening at the bottom for underflow discharge, a larger opening at the top for liquid discharge through an internal “vortex finder”, and a feed nozzle on the side of the body near the cylindrical (top) end of the cone.
Drilling mud enters the cyclone using energy created by a centrifugal feed pump. The velocity of the mud causes the particles to rotate rapidly within the main chamber of the cyclone. Heavy, coarse solids and the liquid film around them tend to spiral outward and down-ward for discharge through the solids outlet. Light, fine solids and the liquid phase of the mud tend to spiral inward and upward for discharge through the liquid outlet.

Hydracyclone is used in our drilling fluids equipment such as desander, desilter, and mud cleaner. It is normally the 2nd or 3rd phase of the mud purifying system.

Spring Blossom

Being the sales of Brightway, the manufacturer of the drilling fluids equipment and drilling fluids system, I sell equipment such as shale shaker, mud cleaner, desander, desilter, centrifuge,mud gas separator, and tank system etc.

The above equipment seems no relationship with my topic-Spring blossom, while I enjoy in my work communicating with people all over the world not only from the aspect of business, but also about life.

I share below lyrics with my customers and my friends all over the world, which I translated from the Chinese song I like.

I like this lyrics because it just tells my feelings to my family.
I believe that we all have something in common.

Spring Blossom


If you desire a drop of water
I'd like to give you the sea
If you want a piece of autumn leaf
I'd give you the maples and the clouds
If you want a smile
I'd like to open my fiery heart
If you need someone to accompany you
I am with you forever
Spring blossom
This is my world
Every bloom
Is love bursting forth
The wind passing by
Is the dialogue between the sky and I
Happiness  actually
Will always be with us

If you want a smile
I'd like to open my fiery heart
If you need someone to accompany you
I am with you forever
Spring blossom
This is my world
Every bloom
Is love bursting forth
The wind passing by
Is the dialogue between the sky and I
Happiness  actually
Will always be with us

Spring blossom
This is my world
Life is like water
sometimes peaceful sometimes surging
Look through the haze
Its sunshine on your window
Happiness actually
Will always be with us
My world
Spring blossom

Know about CBM drilling

What is coal bed methane?

Coal bed methane is natural gas that occurs in coal beds and has been generated during the conversion of plant material to coal (the process known as coalification).

Coal bed methane is produced from a broad range of coal from low rank subbituminous coal through to high rank bituminous coal.

What are the key ingredients for CBM production?

Known, thick, abundant and laterally continuous coal beds

Coal-bearing areas with coals of appropriate rank

Indications of favourable reservoir for accumulation and preservation of coal bed methane

Relatively shallow deposits ~ less than 1,000m

Evidence of fracturing and faulting in coal, correct geothermal gradient

The presence of gas fields producing from coal-bearing rocks



CBM drilling

Brightway CBM drilling mud recycling system is normally with the capacity as 350 GPM and 500 GPM.
The main relative equipment are shale shaker, mud cleaner, centrifuge,mud gas separator, tank, etc.

Where is Brightway?

Our factory name is Brightway Energy Machinery Equipment Co., Ltd, located in the ancient and young city, Xi'an, China. We are the manufacturer of the solids control equipment and complete set of solids control system.
I like the word-Brightway as I'd like to look at the world and life from the bright aspect. Interesting that it is can not been found in dictionary, just a combination word from Chin-English.

Share a picture here of our factory in rainbow, which was a surprising gift I found last month as I had forgotten how many years ago I saw the last rainbow.

Back to the word 'Brightway', I believe a real brightway in the way of your heart no matter the life way rainy,cloudy,windy or sunny.

Why Galvanizing Treatment Much Better Than The Normal Painting Process?

Brightway apply the galvanizing treatment to the solids control equipment and the solids control system.

What is the difference between the galvanizing treatment and the normal painting process?

There are mainly 3 points,and let's have a look one by one.

1. The anti-rust performance of galvanizing treatment is much better than the normal painting process.

In our daily life, normally the galvanizing treatment is applied for the outdoor tubes or the underground tunnels from the consideration of the anti-rust.
The below picture is one corner of the galvanizing factory, from which you can see there are mainly for outdoor or underground use.

We apply the galvanizing treatment on our equipment and system, and in a word, it is to improve the anti-rust performance.

2.For the galvanizing treatment, there is no corner missed in this process,and both inside and outside.

In the below 2 pictures, one is to see the galvanizing treatment inside the tube, the other is to see this treatment inside the shale shaker buffer box.

3.Nice appearance of the galvanizing treatment.

Taking the example of the solids control system, let's see where the galvanizing treatment is applied?

Mud system

shale shaker

mud agitator

hopper
