Method for separating solid phase from drilling mud
Patent
·
OSTI ID:5394652
A method is disclosed for separating solid phase from drilling mud, comprising forming from drilling mud an adhesive layer on a revolving closed curvilinear surface by partially submerging it in the drilling mud and forming from a treatment liquid an adhesive layer on another closed curvilinear surface which is caused to rotate in the direction opposite to the rotation direction of the first curvilinear surface. Both closed curvilinear surfaces are arranged in such a manner that their adhesive layers penetrate one another at a depth sufficient for the adhesive layer of the treatment liquid to take-off coarse solid phase particles from the adhesive layer of the drilling mud. Linear velocities of the adhesive layers are chosen in such a manner that the resultant centrifugal forces are equal to or lower than the centripetal forces.
