Ⅰ. Usage & application scope

JZQJ series Desander is a key member of solids control equipments of drilling fluid that efficiently handle the shale skaker underflow. Its solids control capacity is 30%~50% higher than the past desander, and it can lead to high drilling speed with low cost.

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.

At present time, six types,JZQJ300×2,JZQJ250×2, JZQJ200×2 and JZQJ300×1, JZQJ250×1, JZQJ200×1are 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.
