Ⅰ. Overview and Applications
To meet the needs of oil drilling solid control system production, adapt to the rapid development of drilling technology, and address the issue of low capacity in ordinary centrifuges, our company has designed and manufactured the large-capacity series centrifuges.
The large-capacity series centrifuges utilize centrifugal force generated by high-speed rotation of the centrifuge to make high-density solids in drilling fluid settle and separate under centrifugal action. They can separate solids larger than 5 μm, serving as key solid control equipment on drilling platforms.
These centrifuges are mainly used to control the density and viscosity of drilling fluid, reduce the solid content in drilling fluid, remove harmful solids or recover barite, and perform secondary recovery and utilization of cyclone underflow. These functions ensure the excellent performance of drilling fluid and improve drilling speed. After treatment by the centrifuge, the drilling fluid not only has controlled density and viscosity, but also significantly reduced sand content—this reduces equipment wear, extends equipment service life, and delivers remarkable economic and social benefits.
With rational design, strong adaptability, large processing capacity, simple operation, and convenient maintenance, this centrifuge is suitable for land and offshore oil and gas drilling, coalbed methane extraction, trenchless directional crossing, piling engineering, waste sewage and mud treatment projects. It is used for the fifth-stage solid control treatment of mud and liquids to be processed.
In the large-capacity series centrifuges produced by our company, cemented carbide blocks are inlaid on the conveyor blades to enhance the wear resistance of the conveyor. Additionally, all bearings in key parts are imported, which extends the service life of the entire machine.
