METHOD FOR DEVELOPMENT OF MASSIVE-TYPE DEPOSIT Russian patent published in 1997 - IPC

Abstract RU 2095551 C1

FIELD: oil production industry. SUBSTANCE: increased output of horizontal wells is achieved by nearing injection front to recover zone. Method implies drilling-over of deposit by system of wells with vertical and horizontal bore-holes, injection of displacing agent and recover of product through producing wells. Vertical and horizontal bore-holes are combined in one well. Initially drilled is vertical bore-hole for opening of oil-saturated, water-saturated parts of reservoir and if geological structure of producing bed is of favorable characteristic, horizontal bore-hole is drilled in oil-saturated part in the same well. Then using cyclic procedure, displacing agent is injected into water-saturated part of reservoir through vertical bore-hole, and product is recovered from horizontal bore-hole. EFFECT: high efficiency. 1 tbl, 2 dwg
