METHOD FOR EXTRACTION OF HYDROCARBON DEPOSIT WITH SOLE WATER AND EXTRACTION OF HYDROCARBON BY SUCKER-ROD COMPRESSOR PUMP WITH SEPARATED INTAKE OF HYDROCARBON AND WATER Russian patent published in 2005 - IPC

FIELD: oil extractive industry.

SUBSTANCE: method includes mounting compressor pump in such a way, that input aperture of tail piece was positioned below bed sole. Prior to that water cone in face-adjacent zone is destroyed by draining water through tail piece, connected to lower suck-in valve of compressor pump cylinder, and along behind-pipe space through side suck-in valve of compressor pump cylinder. In case of increase of hydrocarbon contained in drained liquid beginning of water cone destruction is assumed. Draining is continued until destruction of emulsion in water cone, formed in non-homogenous porous environment of bed at limits of hydrocarbon-water and water-hydrocarbon, separation of water and hydrocarbon streams and bringing current water-hydrocarbon contact to initial position. Then during extraction water is drained through tail piece, and hydrocarbon - along behind-pipe space.

EFFECT: higher yield.
