Drilling mud decanter centrifuge is the fourth stage equipments for a drilling mud system.Drilling mud cleaning first stage uses drilling fluids shale shaker ,then second stage uses desander,third desilter,(now drilling mud cleaner is widely used to replace desander,desilter).

drilling mud decanter centrifuge

drilling mud decanter centrifuge

The drilling mud decanter centrifuges can separate fine particles well,for separating 5~7μm particles in drilling mud,usually use medium speed decanter centrifuge,for less then 2μm,usually use high speed decanter centrifuges.

Principle of Operation
Bowl Speed – Depending on the model specification, drilling mud decanter cenrifuges are equipped with either fixed or variable speed arrangement on the main drive enabling the operator to adjust the bowl speed between 1200 and 3850 rpm within a few seconds.  This option, combined with variable conveyor speed, gives a unique dimension to the use of decanters for drilling fluids treatment. The optimum speed for solids removal for a specific cut point depends on the composition of the drilling fluid and the nature of the drill cuttings.

Decanter cenrifuge Scrolling Speed
Decanters are equipped with either fixed or variable back drive. The scrolling speed -(relative conveyor speed) can be changed in a matter of seconds by operations of a simple control switch. The optimum scowling speed is selected in each case according to solids load, required separation efficiency and required underflow density.

Feed Rate – In general a single drilling fluid decanter is capable of a process feed rate of up to 200 gpm. The treatment capacity is influenced by mud type and mud rheology. On drilling rigs it is common to utilize a minimum of two decanters installed in tandem for low weight muds and in series on high-density muds where barite recovery is necessary.

Features of this GLW  355-1250N High speed horizontal decanter centrifuge
a)    Oil gas exploration developer wish to use more clean mud drilling to protect the oil gas layer so as to achieve higher oil gas production.
b)    The using of turbo screw drilling technology put forward higher requirements on the mud cleanness.
c)     More attention will be paid to the disused mud treatment, while treat the disused mud is mainly to separate solid phase from liquid phase as much as possible.

Medium speed centrifuge can separate solid phase granule with the diameter of 5~7μm in low-viscosity mud, as to the thinner granule and high-viscosity mud or the granule in oil based mud, it can not separate them well. So, medium speed centrifuge can hardly meet the new requirements of solid-control system, deploying high speed centrifuge is the development trend in future.
LW355-1250N series of Horizontal high speed centrifuge produced by our company can better meet the above requirements.

GN Solids Control design and manufacture Oilfield Decanter centrifuge with different speed types.

In oilfield drilling mud separation,The larger the centrifugal force, the finer the separated solids, so three types of speed decanter centrifuge can get according to separating factor.

oilfield decanter centrifuge

oilfield decanter centrifuge

a)     Low-speed oilfield decanter centrifuge: it is also called “barite recovery” centrifuge. Its separating factor is 500~700. To low-density solids, its separating point is 6~10μm. To high-density solids, its separating point is 4~7μm. This kind of centrifuge can be used for recovering barite.

b)    Medium-speed oilfield decanter centrifuge: its separating factor is 800 or so, solids of 5~7μm can be separated, so harmful solids can be separated from the mud, so that gravity and viscosity of the mud can be controlled. Most drill team will choose this kind of centrifuge at present.

c)High-speed oilfield decanter centrifuge: its separating factor is 1200~2100 or so, separating point is 2~5μm, it can remove harmful solids, control mud viscosity, it is usually connected with low speed centrifuge to make up a dual centrifuge system(See figure 3). In the system, low-speed centrifuge is installed at the first grade, barite separated
from it is discharged into mud tank to be recovered, liquid is drained into a surge drum first, and then be sent by a pump to high-speed centrifuge; the solid separated from high-speed centrifuge will be discharged out of the tank and the liquid is back to recirculation system. “Dual centrifuge system” can remove

Drilling mud decanter centrifuge

Drilling mud decanter centrifuge

decanter centrifuge,low speed decanter centrifuge.

More over,we can design and manufacture a whole drilling mud management system.With the most suitable decanter centrifuge.

Because there are such a variety of both standard and unique applications, choosing the correct decanter centrifuge is often more of an art than an exact science. Determining the correct machine style and model size requires a thorough understanding of the application and very often sample testing. The more a customer knows about their process and the results desired, the more helpful it is. And when a customer calls or e-mails, we would initially focus on determining the following:

  • Description of the liquid phase and the solid phase for the drilling mud management system.
  • Total liquid volume of the system and amount of available process time and / or required process flow rate
  • Quality of required liquid phase / phases – targeted concentration of impurities
  • Amount of solids that need to be removed from the given liquid volume
  • Targeted dryness of the solids
  • What the customer wants to achieve

Decanter centrifuge in the drilling mud management system are used after the mud Cleaner.As we know the first stage we use shale shaker,and the second,we use mud cleaner.For some drilling mud management system ,we also use vacuum degasser.

From this simple calculation we can often quickly determine which style of liquid / solid separation is most applicable for the application. A further simple lab decanter centrifuge test determines the most appropriate type of decanter centrifuge, whether it fits the customers thinking, and if it is within the expected customer budget.

Industrial decanter centrifuges are wildely used In oilfield drilling fluids solids control systems.It is used after the mud cleaner or desander desilter for seprating drilling cuttings.We are A China based oilfield industrial decanter centrifuge manufacturer.

How Does An Oilfield Industrial decanter Centrifuge Work?

A decanter centrifuge works by spinning a vessel containing the material to be separated at high speed. It is very much like the rides at the fairground that rotate. You have to lean towards the center to overcome the force caused by the rotation. In fact, some rides are designed specifically to press your body against a back support. The decanter centrifuge spins at very high speeds and pushes the ‘heavy phase’, usually the solids, to the outside of the vessel, just as you would see in the clear flask standing on the bench top.

What Is The Oilfield decanter Centrifuge Process?

In the drilling mud purification system,If you take a sample of the liquid / solid mixture in a clear flask and you observe that there is a separation of the two phases with time, the separation is caused by the force of gravity. The oilfield decanter centrifuge process speeds up the process by increasing the force of gravity 1000 to 4000 times, depending on the solids control equipment. The result is that a process that can take 1-12 hours in a flask is achieved in seconds using centrifugation.,

By the way,we also manufacturer shale shaker
