Oilfield Decanter Centrifuge For drilling fluids
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.oilfield Decanting Centrifuge 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.
Mechanical separation of solids from the mud system through the use of a decanter centrifuge is a highly-effective means of maintaining proper mud weight and viscosity. When used in conjunction with otherSolids control equipment, decanting centrifuge enable users to maintain the mud properties within the prescribed range as per the drilling program. Typically,oilfield decanting centrifuge is the final processing units in the arrangement of solids control equipment. Decanting centrifuge preceded by gas busters, gumbo removal equipment (if utilized),?shale shakers,?mud Cleaners?(if utilized),?Vacuum degassers?and hyrdocyclones.
GN Solids Control based in China manufacture and supply complete line of high-speed, variable-speed and fully variable-speed?decanting centrifuge?for handling drilling fluids. Our factory and company are Quality Management System ISO 9001-2000 certified.GN Solids Control operate international oil gas drilling mud separation system¡£ Ruggedly built for oilfield and industrial?Solids control service, decanting centrifuge is especially effective in meeting fluid-on-cuttings discharge requirements in environmentally sensitive areas. decanting centrifuge also deliver high fluid recovery rates and efficient solids control to significantly reduce the operator¡¯s total mud cost and limit waste disposal volumes.GN-China leading?decanting centrifuge?manufacturer with locations in Houston,Texas, USA.
