DEVICE FOR CLEANING DRILLING MUD, CLEANING WATER FROM SAND PRIOR TO BEING PUMPED IN STRATUM, OIL DEEMULSIFICATION

摘要

FIELD: oil production. SUBSTANCE: device has worm conveyor installed to casing with minimum gap. One end of pipe with worm conveyor blades installed is capped, and openings are originated at another end. Liquids, gas being cleaned up are supplied on the side of the cap and twisted by the worm conveyor (worm conveyor is immovable). Heavy fractions are pressed to casing wall under effect of centrifugal force and are removed along tangent through pipe branch. Lighter fractions are removed through openings originated in worm conveyor pipe. EFFECT: higher productivity.
