What we should notice when purchase the shaker screens

Drilling fluid shale shaker is a kind of filterable mechanical separation equipment, compared with other mechanical separation equipment, its unit cost is a kind of economy and high efficiency separation equipment which obtain solid removal amount.

IMG_0371

Drilling fluid shale shaker is made of screen body, machine rack and gearing, according mechanical vibration make solid phase which is big than screen hole and the adhesive attraction will screen the solid phase particles which is smaller than screen hole. But all mud can’t be processed in circulating process because of the limit of shale shaker mud permit.

IMG_0530

Usually the material of drilling fluids shale shaker is stainless knitted. Usually this kind of screen uses mesh to express the specification. Mesh is the number of screen holes. For example, there are 12 holes in a square screen is called 12 mesh. Screen with a special outfit screen holder will screen into flake tension type fixed on the screen frame. Screen body is fixed to the rack according spiral spring, rubber articles bumper use the type of bottom fixed.

shale shaker

When purchase drilling fluid shale shakers except according solid size and particles size distribution to choose the reasonable screen, we should consider a important factor is the permit throughput of mud screen. There are many factors to affect drilling fluids shale shaker throughput. Such as the type of mud, proportion,viscosity, solid content and size, screen number and ect.

Solid control desander and desilter from China Manufacturer

DC Solids Control provides a large number of solid control system and waste treatment system products to customers worldwide every year.

DC Solids Control desander is mainly used to remove drilling cuttings larger than 55 microns in drilling fluid. The drilling fluid purification sand remover is mainly composed of underflow screen and 10 inch sand removing cyclone. Under normal circumstances, the centrifugal pump is used to feed the desander.

desander

The cyclone uses a centrifugal pump to pump the mud into the swirl cone at high speed, and centrifugally separates the mud under the action of centrifugal force. After centrifugal separation, the lighter mud flows out of the cyclone outlet. The mud with high solid phase is ejected through the drip nozzle, and further sieved and separated through the underflow screen.

desilter

The structural principles of DC Solids Control Desilter and Desander are similar. The only difference is that the cyclone used in the desilter is a 4-inch cyclone. Generally, the number of desilting cyclones is an even number. Desilter is mainly used to remove solid cuttings larger than 25 microns in drilling fluid.

Besides above the separated desander and desilter. DC Solids Control also provides ‘3 in 1’ treating unit which is ‘DC Mud Cleaner’, it’s composed by 10 inch cyclone, 4 inch cyclone and bottom shale shaker. Every year. Welcome to connect with us if you need any solids control equipment.

Why must use the decanter centrifuge in working site

The structure and performance of drilling fluid centrifuge all have a bid progress, our country have already special mud centrifuge designed accords the characteristics of drilling fluid. Drilling fluid centrifuge is the most difficult master and the structure is complex equipment. But it is the key equipment except shale shaker.

The initial stage of decanter centrifuge became solid control system is the chemical centrifuge is introduced. Not only the separation size or capacity all can’t meet the requirement of drilling fluid solid control technology.  Now decanting centrifuge has the characteristics.

decanter centrifuge

The capacity from small to large, foreign has already the centrifuge can dispose 4T material per hours.

It has common centrifuge and high speed centrifuge. The common centrifuge can’t solve the whole problems of drilling fluid. High speed centrifuge can dispose drilling fluid, the disposing drilling fluid become dry material and water two parts. Using it to process drilling fluid can maintain environment and ecological environment.

oilfield centrifuge

The transmission structure evolves ingle motor drive from double motor.

The prime centrifuge is chemical centrifuge, the drum and conveying screw are all use stainless steel to manufacture. In recent years we have already research the drilling fluid solid cobtrol special centrifuge with the material of drum and conveying screw is carbon steel, so the cost is decreased.
The abrade level of drum and conveying screw has the structure of using bonding method dressing pad the ceramic disk, it can improve the service life of centrifuge.

Drilling fluid mud gas separator Application

Drilling fluid mud gas separator is a special equipment of gas cut drilling fluid primary degassing, it is mainly used to eliminate the bubbles which the diameter is about3-25mm. The big bubbles is aiming at the expansion gas which is fully the borehole, if it is not eliminated, it will causes the well kick even spurt the surface of drill plate. The equipment uses the prevent sulfur material and adapts the gas with H2s processing.

Liquid gas separators

Working theory

The gas cut drilling fluid enter into separator from the separator inlet month, after impacting with the impact plate, scattered in a series baffle, crashing and increase and reveal the surface area, then downward flow causing the flocculated flow state, make the gas separation with drilling fluid. The free gas is discharged through the gas outlet of the top tank, the length of the exhaust pipe is decided and installed by the field and is lead to the safe place, but the after degassing drilling fluid flow into circulating tank through drilling fluids shale shaker.

mud gas separator

Installation

It is installed in the ground near the 1 circulating tank, using the wire rope fixed the lifting lug place up the separator main body with the ground.
According the requirements of diagram form to connect the line after install well.

Maintenance

We should check the bottom buffer plate when use it, we must replace the two baffle if the wearing is extend 10 mm.
The drilling fluid in mud gas separator should be emptying after use (especially in winter) and open the cleaning month or the entrance is cleaned

3 The stirring intension of drilling mud agitator is strong, extensively affected and decrease the starting resistance.
4 The motor of drilling mud agitator place in a horizontal position, it is convenient to install and adjust.

agitators

The structure and working theory of drilling mud agitator

Structure: the device is mainly made of explosion proof electric machine, reducer, engine base and impeller components, reducer and motor, reducer and wave wheel are all connected with solid coupling. The wave is made of four impellers weld.

Working theory: The wave can make agitate fluid produce vortex motion and enhance the mixing effect. The tray caught in the middle of the blade can avoid the mud solid phase deposit on the round of lower impellers after stopping, such use can reduce the resistance moment of the sediment to impeller, it prevent burn motor when starting overload.
