Solid control system, also referring as mud system, is used to separate the solids or gas from the drilling mud. There are several centrifugal mud separators such as hydro-cyclone separators (desander and desilter) and decanter centrifuge, and mud gas separator, which separate drilling mud and gas.

Hydrocyclone Separator

Hydrocyclone separator is always referring as desander and desitler, used after shale shaker in the solids control system. Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4” cone to separate solid-phase particle size 15-47μm in the drilling fluid.

Decanter Centrifuge

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Continue reading »
