Low speed centrifuge

The main function of low speed centrifuge in solid control system is throwing the barites and aggravating solid phase particles out of drilling fluid and recycling utilization to control drilling fluids density. The economic benefit to dilute drilling fluid to control drilling fluid density is very obvious.


High speed centrifuge 

The high speed throughput is smaller 5 times than medium speed centrifuge, and it can dispose the fine solid phase particles, it can’t separate high solid phase density drilling fluid. So it must used matching with low speed centrifuge. But the solid phase processing range of high speed centrifuge is influencing the solid phase range of drilling fluid viscosity. So high speed centrifuge has the good effect to decrease drilling fluid shearing force in deep well, improve well quality and prevent down well accident.

3-Phase horizontal centrifuge China supplier

The 3-Phase Separating Decanter is a centrifuge in which two liquids of different densities are separated from each other. At the same time solids are separated and discharged. 3-Phase centrifuges are widely used in oilfield at present.

A three-phase centrifuge is capable of three distinct phase separations in a single pass. Three-phase centrifuges are uncommon in the petroleum industry, but have been used in other industries. The oil field separation is a far more difficult problem, because the oil field mixture is a solid-stabilized emulsion produced from a liquid-solid. This 3-phase separation horizontal decanter centrifuge is primarilly employed for solid-liquid-liquid separation, namely the simultaneous separation of one solid phase and two immiscible liquid phases with different densities. The premise is that the solid phase is the heaviest.

3-phase centrifuge

Separation process of 3-phase centrifuges 

The feedstock enters the decanter through feed tube and flows into the centrifugation space through the distributor. The conveyor screw transports the solids to the solids discharge. The level of the liquid can be adjusted by fitting regulating rings or disks of the required inner diameter. Separation of the two liquid phases takes place in the separation zone, whereby the light phase flows towards the bowl axis, and the heavy phase towards the bowl wall.

Working principle

Under the centrifugal force, the material will be formed with three relatively stable layers including solid phase layer, as well as heavy and light liquid layers, from the bowl wall to the inside. The solid phase will be driven to the small end of the rotary bowl by the screw conveyor and then will be expelled from the slagging hole. The heavy and light liquid phases will flow towards the big end of the rotating bowl along passages among screw flights and then will be drained from different outlets. Therefore, the continous 3-phase separation achieved.

DC Machinery is a specialized 3-phase separation horizontal decanter centrifuge manufacturer and supplier in China. We offer a vast range of products, including high speed centrifuge, 2-phase separation horizontal decanter centrifuge. If you have any requirements, please contact us.

Characteristic introction of decanter centrifuge

The word “ decanting means pouring of liquid so slowly that any sediment in the bottom remains undisturbed.
The centrifugal force created by the centrifuge depends on the diameter and Rpm of the bowl. Use the following formula to calculate
“ G” force:  G=(RPM)2 (0.0000142) (Diameter of bowl, in ).

The performance of decanter centrifuge for a given mud depends on the following factors:
1. The G’ exerted on the fluid.
2. The retention time of the fluid in the centrifuge.
3. Conveyor speed.


The following factors are considered in different designs and applications:

1. Bowl diameter
2. Length of bowl (increases retention time )
3. RPM operating range
4. Conveyor speed
5. pool depth

The rate at witch a particle will settle is directly proportional to the force of gravity , the square of its diameter and the difference in density between liquid and the medium in which it is settling. It is also indirectly proportional to the viscosity of the liquid.

In weighted mud, the application of centrifuges is some what different. In general, two centrifuges are used. One unit is used to remove the weight materials and the second one is used to remove drilled solids. The clean mud is then returned to the achieved system where it is re- united with the recovered weight materials.

Why use solid control system in oil&gas drilling

Drilling mud is a obbligato part in petroleum drilling. It has highly polluting properties. As followings;\

Drilling muds contain a wide range of substances including base fluids (eg mineral oils/calcium chloride), weighting agents (eg barite), viscosifers (eg bentonite), surfactants (eg imidazolines) and biocides (eg glutaraldehyde).


Mud can aDrilling mudlso contain contaminants from formations (eg oil, condensate and H2S).

Hot mud will generate mists and vapours.

Health effects include dermatitis, respiratory irritation, narcosis and cancer.

H2S is a very toxic gas, it can irritate the eyes, and throat and can cause unconsciousness and death.

Good practice benchmark values for total oil vapour is 50 mg/m3 and oil mist is 1 mg/m3.

Individual substances should comply with their workplace exposure.

solid control system

Following the development of social economy, Each country is very strict to the environment but can’t restrict the development of economy. So appear solid control system to separate it. Solid control is a professional application to treat and recover the drilling mud.

Solid control system mainly consist of 5 levels( shale shaker, desander, desilter and decanter centrifuge). It not only can remove the harmful solid phase, but also can recycle the useful mud. That meas, protection the environment and reduce the drilling cost. Solid control system also become the obbligato part in petroleum drilling.
