Oilfield drilling mud desander for mud process


Desander fulfill separation on drilling mud large drilling cuttings. It is second class solids control equipment. Various size desander cones are functionally identical, with the size of the cone determining the size of particles the device removes from the mud system.


The cones size and number can be adjusted according to client's actual capacity requirements. Cones also can be cast iron or other materials. The bottom shaker can be configured or not.


Drilling fluid desander is a hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shaker and vacuum degasser, but before the desilter or mud cleaner.

Cyclone desander is designed by the principle of particle sedimentation, the drilling fluid enters into inwall of swirler, the thicker particles spiral sinking with the action of centrifugal force and gravity, discharged from bottom exit, and separated by shale shaker, the other liquid spirals along the swirler, enters into the third-level separation equipment – desilter from overflow port to dispose further.

In fact, drilling mud desander can be widely used in many industry and project. Not only in oil well drilling but also for HDD, CSM exploration, geothermal well, water well drilling, slurry separation, etc.
