ABSTRACT:
The drilling fluid of deviant composition is subjected to a separating process comprising two stages, including a sieving stage and thereafter a pressure filtration stage, the drilling fluid clinging to the sieve residue obtained in the sieving stage is sucked off by means of a partial-vacuum, the liquid obtained in the separating stage is used for adjusting the desired composition of the drilling fluid in the supply container thereof, and the solid material separated in the separating process is dried and further processed for recovering the solid material to be used in the drilling fluid.
