Zusammenfassung:	PCT No. PCT/SU79/00090 Sec. 371 Date Sep. 16, 1980 Sec. 102(e) Date Sep. 11, 1980 PCT Filed Sep. 28, 1979 PCT Pub. No. WO80/01495 PCT Pub. Date Jul. 24, 1980.A method for the preparation of drilling mud wherein solid and liquid phases of drilling mud are mixed in a vessel (2) to obtain a homogeneous suspension. After the mixing the drilling mud is caused to pass under pressure through apertures (5 or 6) provided in a stirring member (3 or 4) of a piston type, the apertures being of a diameter which is greater than maximum size of an individual solid phase particle but smaller than the diameter of aggregates of particles, to prepare dispersed drilling mud.
