Drilling fluid, known as the mud, has several different functions to drill an oil or gas well, including subsurface pressure control and cuttings removal, which also reduces the friction between drill bit and the wellbore.

When the Drilling rig is working, the drilling cuttings that chipped away by the bit goes into the drilling fluid and its technical parameters like density, viscosity and special gravity will be changed and could not meet the drilling’s requirements, seriously the Well Kick or Well Blowout could be happened.

The drilling fluid circulated the cuttings to the surface, as the sizes of cuttings in the drilling fluid are different, in order to promote the treatment efficiency and effect, usually the cuttings needs to be separated out by adopting multiple-stage separation. The Shale Shaker is matched together with the Desander, Desilter and sometimes the Decanter centrifuge is also equipped, to treat the drilling fluid and recover its physical properties.

Normally the Shale Shaker is used as the 1st-stage drilling fluid purification equipment. It is mainly used for screening out the big size cuttings like over 100μm. The working principle is as below:

  1. The fluid pump circulates the fluid from the fluid pit to the Shale Shaker;
  2. There are vibration motors installed on the Shale Shaker. The motors produce shaking force and the fluid moves on the Shaker Screen.
  3. The big size cuttings could not go through the Shaker Screen and are discharged. The treated drilling fluid will go to the next-stage for continuous cleaning.

Based on the different requirements of customers from different industry, GN could provide the standard shale shakers and customized ones for customer option. Such as different treatment capacities, different types of shaker screen, different combinations of Shale Shaker with Desander or Desilter, Desander and Desilter together.
