A METHOD OF PURIFYING DRILLING MUD OBTAINED FROM DRILL HOLES BY SEPARATING THE SOLID PHASE FROM DRILLING MUC

摘要

A method of purifying drilling mud obtained from and holes comprising the step of separating solid phase form drilling mud, which includes forming from drilling mud an adhesive layer on a revolving closed curvilinear surface be partially submerging it in the drilling mud and forming an adhesive layer of a treatment liquid on another closed cruel near surface by partially submerging it in the treatment liquid and causing it to rotate in the direction opposite to the portion direction of the first revolving curvilinear surface both closed curvilinear surfaces being arranged in such a summer that their respective adhesive layers penetrate one another at a depth which is sufficient for the adhesive layer at the treatment liquid to take-off coarse, particles of solid phase form the adhesive layer of the drilling mud, the linear velocities of the adhesive layers being chosen in such a manner that the resultant centrifugal forces be equal to or lower than the centripetal forces.
