Solid Control Equipment
Decanter Centrifuges/ Oilfield Centrifuge
Mechanical separation of solids from the mud system through the use of a centrifuge is a highly-effective means of maintaining proper mud weight and viscosity. When used in conjunction with other solids control equipment, centrifuges enable users to maintain the mud properties within the prescribed range as per the drilling program.
Working Principles
Centrifuges rely on the use of centrifugal force, generating several hundreds or thousands of times earth’s gravity. It is composed of a conical drum that rotates at 2000 to 4000 rpm. Drilling fluid is fed into one end and the separated solids are moved up the bowl by a rotating scroll to exit at the other end.
They are available individually, in groups, or packaged as a component within a complete solids control and waste management solution. Centrifuges are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.
