  • The Working Principle Of Oilfield Desander


Oilfield desander is handling secondary drilling fluid solid control equipment, according to the size of the cyclone diameter is different, divided into cyclone oilfield desander and desilter spiral flow. Combination known as generally more than 6 "hydrocyclone oilfield desander, is the secondary solids control equipment in drilling operation, is commonly used, 10" and 12 "hydrocyclone separation is mainly used for drilling fluid in the granularity of 47-76 microns of solid phased particles. According to the size of the customer request processing, choose several groups of cyclone oilfield desander. Cyclone oilfield desander is widely used in oil drilling, desanding separation of trenchless horizontal directional drilling.


The working principle of oilfield desander

Oilfield desander is the combination of hydrocyclone oilfield desander and vibrating screen. Cyclone oilfield desander is designed according to the principle of particle sedimentation, the drilling fluid separation medium through sand pump produce a certain pressure and velocity, along the spiral into the cyclone wall, coarser particles under the action of centrifugal force and gravity, the cyclone wall spiral sink, from the bottom lunderflow orifice, falls below breakdown vibrating screen separation, has risen in a spiral along the hydrocyclone, the rest of the media from the overflow mouth into the third grade separation equipment desilter further purification treatment.
