Decanter centrifuge application for drilling rigs

Decanter centrifuge is a very important machine for oil & gas drilling rigs. Usually at least 2 sets decanter centrifuge should be used for 1 drilling rig.

The first centrifuge with middle speed acting as the fourth phase solids control equipment. It is used for recovery barite. Barite is an expensive material for drilling mud. A good barite recovery centrifuge can help to reduce drilling cost.

The second centrifuge will be used for treatment of the drilling cuttings. Usually, for OBM and SBM, it is used after vertical cuttings dryer. For WBM, after high G shaker. It is used to cover useful drilling mud from drilling cuttings.

World top decanter centrifuge model for drilling rigs:

1) Derrick (DE-1000) decanter centrifuge

2) MI-Swaco (518) decanter centrifuge

3) GN Solids Control: GNLW363 decanter centrifuge

Why choose GN brand decanter centrifuge

The former 2 brand is formerly the most famous for decanter centrifuge for drilling site for a long time. But their price is relative higher. Or say, much higher. In this case, market urgently needs a new brand with good quality, reliable service, good brand name, but more cost-effective price. GN Solids Control comes out with its most hot sale model GNLW363 and GNLW553 centrifuge. Both of the decanter centrifuge model can be matched for fixed speed or variable speed with PLC control panel.

Many drilling rig they not buy decanter centrifuge with mud recovery system as the high cost. They rent from special mud service company while needed. And they pay for every day. Actually, it is a huge cost for the long run. Now, GN Solids Control enable them another option. Contact GN now, then you can own your own centrifuge for your rigs: good price centrifuge model for option

Decanter centrifuge is one part of the solids control system, and sometimes it is used separately, for diamond drilling works, some coring works in mining industry, other drilling works with small debries.

As we know, in solids control system for oil&gas drilling, after the third phase, the desilter, debries bigger than 30 (15-47) microns are cleared out.

Once a client told us that they use mi swaco 414 with tank as a centrifuge system for their diamond drilling, we find we producing the equivalent one, LW220. So after proved with our experenced engineer, then re-researched by the cooperation universities, we manufactured our own centrifuge system for diamond drilling. LW220 with mud tank. Rugged design, compact body, efficient solution.

The differential gear type is mechanical differential, and the treating capactity is ≤ 150lpm, which means the maximun capacity is 150lpm, and you even can use this to handal the drilling mud with about 20lpm.  Other specific is as shown below:

Drum diameter: 220mmlw 220 centrifuge

Rotary speed:1500~4800rpm (Variable Speed)

Brief introduction

Decanter centrifuge is the fourth class solids control in drilling mud separation system. Decanter centrifuges used to separate more fine particles from drilling cuttings.

GN drilling mud processing system is a complete “closed-loop” re-circulating liquid filtration / fluid clarification system typically applied to glass, ceramic, and metal grinding coolants as well as other industrial fluids.

The main structure and simple principle of GN Decanter centrifuge

The solid wall bowl has a cylindrical section for good separation and clarification of the liquid and a conical section for dewatering the solids. The product enters the decanter through the feed and is led into the separation chamber via the distributor. Under the action of centrifugal force, the solid particles sediment on the bowl wall and are conveyed to the solids discharge by the scroll. On decanter the clarified liquid flows off under gravity whereas on decanter type the liquid is discharged under pressure by means of centripetal pump.

Centrifuges can be customized

Centrifugal filtration equipment By matching the appropriate tank size and capacity requirement, decanter centrifuges are designed and configured to suit each customer’s individual application. GN will size, design, and configure a decanter centrifuge that suits your facility and specific application requirements.

LWF Decanter centrifuges are designed to provide a continuous and consistently low minimum level of suspending solids and extend the life of the working liquid / fluid while providing a low maintenance and environmentally effective method of separating and handling the separated solids / sludge.
