The circulation system of the drilling rig is equipped with a four-stage cleaning system for cleaning the drilling fluid, including a vibrating screen, a sand separator, a sludge separator and a centrifuge. In the case of high drilling mud design density, centrifuges are turned on regularly, that is, they are actually density regulators.

 

 

Only the vibrating screen is used to remove heavy drilling fluid from the sludge, because the hydrocyclone mechanism removes barite from the solution along with the sludge due to centrifugal sedimentation. For weighted solutions, the purpose of the centrifuge is to regenerate the weighting agent and return it to the solution. When drilling holes in clay deposits, the solution develops rapidly, its viscosity increases, and it is discharged into the dump along with the weighting agent in a significant volume. Reducing the viscosity through dilution can only be carried out to a certain content of clay colloids, and it is necessary to introduce chemicals and weighting agents to maintain the density.
 

Therefore, a modern system for cleaning the weighting solution should include a centrifuge and a barite agitator, which returns the weighting agent from the excess solution to the circulation, and discharges the liquid phase with colloidal components into the barn. This operation is carried out according to the washing cycle together with the simultaneous introduction of an aqueous chemical solution to maintain the required density.
