FIELD: oil and gas production industry, particularly to operate oil and gas (gas condensate) wells requiring reservoir pressure keeping. ^ SUBSTANCE: method involves connecting two reservoirs, namely water-bearing and oil-bearing ones, in well by casing pipe perforation, wherein some branched holes of well including at least two holes expose only oil-bearing reservoir, other ones are drilled simultaneously in water-bearing and oil-bearing reservoirs; communicating branched holes or hole exposing oil-bearing reservoir with well head; isolating branched holes or hole exposing oil-bearing reservoir along with water-bearing one from well head. Bypass water flow is controlled by flow meters and water-flow regulators. ^ EFFECT: increased efficiency of oil field exploitation due to decreased number of producing and injection wells and elimination of water injection system(pumps, pipelines), which supplies water to reservoir. ^ 2 cl, 2 dwg |
