METHOD FOR DEVELOPMENT OF OIL DEPOSIT WITH WEDGING-OUT ZONE

摘要

FIELD: oil production industry. SUBSTANCE: reduced cost of injecting displacement agent and increased oil output are achieved by locating injection holes along lines of reservoir wedging out. and positioned in close proximity to them and parallel to lines of reservoir wedging out are holes of producing wells or rows of vertical producing wells. Reagent is pumped into injection wells after reservoir pressure in these wells rises above initial value by 5-10%. EFFECT: high efficiency.
