Drilling mud desander is the second class solid control equipment to treat the drilling fluid. According to the size of the cone diameter, it is divided into desander hydrocyclone and desilter hydrocyclone. Usually the cone diameter is more than 6?is called Desander, and used as the second-control equipment in drilling fluid solids control system. We commonly used 8 "and 10" cones desander to separate solid-phase particle size 45-76µm in the drilling fluids. Desanders are installed on top of the drilling rig mud tank following the shale shaker and the degasser, but before the desilter. Desander removes the abrasive solids from the drilling fluids which cannot be removed by shakers. Normally the solids diameter for desander to be separated would be 45~74µm, and 15~44µm for desilter.A desander is able to remove 50% of solids within the 45-76µm range at a flow rate of 500 US gallons per minute (32 L/s), whilea desilter (4 inches (100 mm) Cone) is able to remove 50% of solids within the 15-44 µm range at a flow rate of 60 US gallons per minute (3.8 L/s). Micro-fine separators are able to remove 50% of solids within the 10-15 µm range at a flow rate of 15 US gallons per minute (0.95 L/s). A desander is typically positioned next-to-last in the arrangement of solids control equipment, with a decanter centrifuge as the subsequent processing unit. Desanders are preceded by gas busters, gumbo removal equipment (if utilized),shale shaker, mud cleaner (if utilized) and a vacuum degasser. Desanders are widely used in oilfield drilling. Practice has proved that hydrocyclone desander is a kind equipment of economic and effective.
