close loop mud system

Recently drilling has been changed a lot, the old experience did not work, people has their own new design. “Zero discharge mud systems” are urgently required because of the environment protection. Auger box, screw conveyor can be used to collect the drilling cuttings from shale shaker, desander, desilter, mud cleaner, dewatering unit and centrifuge, then transfer them to a catch pit for later processing. In some development company where the government did not have strict regulation on environment protection, they even do not use any mud system, and let the drilling fluids discharged directly. They may face big problem in the future.

Dewatering unit is required to work together with the system, it can make further process of the fluids after processed by centrifuge after the well is finished.

The mud tank is designed similar to 40 feet standard container, it is more convenient to transport in any countries in the world. All the lifting device, dimension, skid is same with container, and we put GN solids control equipments on top of it.

If you required Close Loop mud System for oil & gas drilling, pls contact GN solids control, our service including design, consultant, manufacture and shipment.

By Oilfield glossary, sand control is one of the process of well completions. “The installation of equipment or application of techniques to prevent migration of reservoir sand into the wellbore or near-wellbore area. In weak formations, sand control may be necessary to maintain the structure of the reservoir around the wellbore. In other formation types, the migration of sand and fines into the near wellbore area may severely restrict production. Each of these conditions requires different treatments. The principal sand-control techniques include gravel packing and sand consolidation.”

sand control

Sand control focusing on gravel packing, the most popular choice.

What is Gravel packing?

Gravel packing involves the complete placement of selected gravel across the production interval to prevent the production of formation fines or sand. Any gap or interruption in the pack coverage will enable undesirable sand or fines to enter the producing system.

It includes the following components:

1 production tubing

2 production casing

3 Gravel-pack packer

4 Gravel placed in casing and perforations

5 Gravel pack screen

6 Sump packer

Sand control V.S. Solids control

Sand control has always played an important role in oil production, but solids control plays an important role in oil well drilling. They are utilized in different area.

Solids control is a technique used for well drilling to provide prepared drilling fluids for drilling rigs. 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.

solids control equipments

GN manufacturer complete sets of solids control equipments( shale shaker, desander, desilter, mud cleaner, decanter centrifuge, centrifugal pump, vacuum degasser,mud agitator, mud gun, mud tank, etc), also we can recommend good companies for sand control in China.

decanter centrifuge to Ecuador

How a decanter centrifuge works

A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity.

When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required.

The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually “ploughed” out of the pond and up the conical “beach”.

The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl. Baffles within the centrifuge casing direct the separated phases into the correct flow path and prevent any risk of cross-contamination. The speed of the screw conveyor may be automatically adjusted by use of the variable frequency drive (VFD) in order to adjust to variation in the solids load.

Recently GN sold another set of decanter centrifuge to Ecuador by air. Usually it is difficult to ship the large equipment by air. GN can provide clients for complete service including shipment or recommend some good freight forwarder with rich experience for the large equipments. The limit dimension of GN decanter centrifuge model GLW355x1250N in transportation is 3x2x1.47m, which is accepted by air freight company, and we can provide package service for client’s requirement.

decanter centrifuge for sale

GN decanter centrifuge mainly used for drilling fluids processing, barite recovery, drilling waste treatment, mud weighted, etc projects. We also produce related equipments fitted for the centrifuge, to be assembly as a complete drilling mud processing system, including mud tank, mud agitator, mud mixer, shale shaker, etc.

Safety Device of GLW-V-355x1250N decanter centrifuge

1. Anti-overload

The device protects the Compensating gear from torque overload, which is installed in the outside end of the Compensating gear. The torque of gear is limited with a spring clutch by which power can be imputed. While overload cuts off spring clutch with driving shaft, the face of spring move the gland down to outside for 6mm and the stroke faucet switch on to switch off the power of main motor and fluid supply pump.

1. Electric interlock device (only dual motor driving system)



In the dual motor driving system without inverter speed-adjustable device, the correct program for starting a centrifuge is:

1)        Firstly start the auxiliary motor.

2)        After thirty second, the main motor allows to be started.

The correct program for stopping a centrifuge is as follow:

1)        Firstly stop the main motor.

2)        After ten minutes, the electric interlock device will automatically switch the power of the auxiliary motor.

With the electric interlock device, the correct program can be automatically carried out and unexpected result from wrong operation can be avoided.

GLW-V-355x1250N Advantages:

1. width rotary speed to satisfy technical requirement;
2. Smooth and silence when start;
3. Small start electrical current is safe to power supply system;
4. Save power more thirty percent than conventional centrifuge;
5. Operation of modulating speed is simple and various speed can be got;
6. Quickly show system. The digital rotary speed of centrifuge can be controlled accurately and shown on LCD screen.
