METHOD FOR DEVELOPMENT OF OIL FIELD Russian patent published in 1998 - IPC

FIELD: oil-producing industry; may be used in development of oil pools. SUBSTANCE: method includes injection of working medium through injection wells in cyclic mode; treatment of bottom-hole formation zone of producing wells; oil withdrawal through producing wells. Prior to treatment of bottom-hole formation zone of producing wells, subject to determination is formation pressure, production rate and rate of growing of water encroachment of each producing well. In cycle of working medium injection through injection wells, bottom-hole formation zone of producing wells featuring high formation pressure and low production rate are subjected to treatment. In idle cycle of injection wells, bottom-hole formation zones of producing wells with high rates of growing water encroachment are subjected to water repellency treatment. EFFECT: higher oil recovery from pool.
