Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally solid control system is consist of five stages, including mud tank, oilfield shale shaker, vacuum degasser, desander, desilter, centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as high efficient mud cleaner. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of the mud tank. After separating the solids, the clean mud would be pumped into the borehole again.
KOSUN DC series drilling fluid decanter centrifuge is used in drilling fluids processing system for separating suspension of solids phase with particle diameter（d≥2μm） for drilling mud circulation and drilling fluids recycling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The oil drilling mud decanting centrifuge must test the dynamic balance for smooth operation over long periods.Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.
Features & Benefits of Decanter Centrifuge
1. Innovative design includes longer bowl for increased retention time, resulting in drier solids and finer cut points.
2. Big bowl Big Volume, high G force available.
3. Stainless steel bowl, scroll, compartment and cover resist corrosion and provide long service life.
4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
5. German FAG or Sweden SKF brand bearings.
6. Electrical Components: SIEMENS/Schneider ATEX or IEC Ex for option.
7. Screw pump & drilling mud centrifugal pump feeding pump option available to meet different application.
