Five Phases Drilling Solids Control Equipments

If you are involved in the field of oil & gas drilling, you must know drilling company often need drilling solids control equipment such as shale shaker, desander, desilter etc. to treat drilling fluid and recycle it.

Many industry insiders know the five phases drilling solids control equipments, but do you know it? Generally speaking, in proper order, they are separately shale shaker, vacuum degasser, desander, desilter, decanter centrifuge.

Shale shaker: Shale shaker is widely known as a solids control equipments used in drilling projects. It is a very basic equipment that could separate the drilling cutting more than 250 microns by fine mesh screens. During this stage, actually, the solids control and purification happens at the same time. Just as its name implies, solids control is separate the solids from the fluids, while the drilling cutting and other large size impurities being separated, the drilling mud is purified.

Vacuum Degasser: A vacuum degasser could be functioned as the second stage purification equipments. During this stage, there is no solids separated from the drilling mud, just the invasive air is removed. Why must remove the air from the drilling mud? Invaded air could reduce the specific gravity of the mud and make the centrifugal pump work at low efficiency. 

Desander: After treated by vacuum degasser, drilling mud is feeded in to desander by centrifugal pump. The main parts of 1 set desander are the hydrocyclones. Desander cone could separate the solid particles with size of 45 microns.

Desilter: Same working principle with desander, desilter cones separate the particles of 16 microns. Desander differs desilter by the size of hydrocyclone.

Decanter Centrifuge: You will see this stage equipments in large mud system for oil & gas drilling. One or more set decanting centrifuge is the leading role in this stage. By centrifugal sedimentation principle, it delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal.


As a China solids control company, KOSUN can provide a complete line of solids control equipment for the oilfield Industry and the environmental Industry for over 20 years. KOSUN can provide customers with several series as oil & gas drilling solids control equipment, centrifuges and drilling waste management equipment, etc.
