Product details


Solids control system is used in oilfield drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Oilfield solid control system is consist of shale shaker, vacuum degasser, desander, desilter, centrifuge. Oilfield drilling shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for drilling fluid desander, and 15~44μm for Oilfield drilling desilter. Vacuum degasser is used to separate the air, if air enters into the drilling fluids. KOSUN is a oilfield drilling mud desander manufacturer in China


KOSUN Oilfield drilling mud desander


Oilfield drilling mud desander is the second stage and the third stage solid control equipment to treat the drilling fluid.Hydrocyclones is also called cyclone separator.Hydrocyclones consist of desander(10 in. cone) and desilter(4 in. cone)are drilling rig equipments with a set of hydrocyclones that separates sand and silt from the drilling fluid. Desander is installed after shakers and degasser but before desilter. Desander removes those abrassive solids from the drilling mud which cannot be removed by shakers. We commonly used 8 "and 10" cones desander to separate solid-phase particle size 47-76μm in the drilling fluids.Desander and desilter are combined as oilfield drilling mud cleaner.Oilfield drilling mud cleaner is the best choices for small oilfield solids control system for HDD,CBM, water well drilling, mining exploration industry etc.


KOSUN Drilling mud desander structure

Drilling mud desander have moving parts. The larger the internal diameter of the desander is, the greater the amount of drilling fluids it is able to process and the larger the size of the solids removed. Drilling mud desander with a (10 inches cone) is able to remove 50% of solids within the 40-50 μm range at a flow rate of 500 US gallons per minute (32 L/s), while a oilfield drilling desilter (4 inches (100 mm) Cone) is able to remove 50% of solids within the 15-20 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). Oilfield drilling mud desander is typically positioned next-to-last in the arrangement of solids control equipment, with a drilling 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.Oilfield drilling mud desander are widely used in oilfield drilling.
