GN solids control can manufacture middle speed, High Speed & Variable Speed decanter Centrifuge according to the customer’s requirements.

With the improvement of petroleum drilling technology and environmental protection awareness, higher requirements are put forward to the petroleum drilling solid-control system, mainly embodies in the following three aspects:

high speed 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.

GLW355-1250N series of high speed centrifuge produced by our company can better meet the above requirements.

Separating principle of centrifuge

The separating process of solid phase and liquid phase in mud is completed in the roller. The separating principle is to use the high speed rotation of the roller to drive the mud entered into roller to rotate at high speed, the mud is thrown onto the wall to form a liquid circle, the solid phase granule in the liquid circle is influenced by the centrifugal force, which is hundreds times or even thousands times heavy than itself will then overcome the resistance of mud viscosity and rapidly drop onto the wall of the inner wall of the roller, form the solid phase layer, and the liquid form the liquid phase layer. The ratio between centrifugal force of the solid phase granule in liquid circle and its own gravity is called the separating factor, which is an important parameter in scaling the separating performance of the centrifuge.

  1. Oil-based mud desilting Says:

    […] Oil-based mud can be a mud where the base fluid is a petroleum product such as diesel fuel. Oil-based mud are used for many reasons, some being increased lubricity, enhanced shale inhibition, and greater cleaning abilities with less viscosity. Oil-based mud also withstand greater heat without breaking down. The use of oil-based mud has special considerations. These include cost and environmental considerations. […]
