At present time, four types, ZQJ300×2/ZQJ250×2 and ZQJ300×1/ ZQJ250×1,are available. The former applies to over 3000-meter-long drills, and the latter applies to small drills of less than 3000 meters and service rig.
When passing through the feed manifold, the pressured drilling fluid flow into the hydrocyclone in the direction of a tangent and spirally revolve downwards with high-speed. The drilling fluid bleed into mud tank through overflow gate and the solid in the mud is cut into the underflow that is drained to shaker screen due to the centrifugal generated by revolution.
Desand is the second class and the third class control equipment to treat the drilling fluid.
Usually the cone diameter is more than 6" is called desander and used as the second-control equipment in drilling operation
we commonly used 8" and 10" cones desander to separate solid-phase particle size 47-76um in the drilling fluids
it apply for directional drilling
Usage & Application Scope
As a solids control equipment of the second stage in drilling operation, desander is used to remove harmful solid particles of 40-74µm in drilling liquid. Suspending particles can be separated from the liquid under the centrifugal acceleration, by use of working principle of centrifugal subsidence.
