FIELD: oil-and-gas production.
SUBSTANCE: method includes drilling of producing and injection wells, pumping of displacement agent through injection wells, withdrawal of production through producing wells, definition of boundaries of substitute areas of collectors and withdrawal of stratum product from dead spaces nearby zone of collectors replacement. There are defined areas of band discontinuity of collectors, it is implemented drilling of additional producing wells nearby areas of band discontinuity of collectors replacement from the side of injecting wells.
EFFECT: increasing of oil recovery, increasing of oil extraction ensured by involvement into development of dead areas of oil, located nearby areas of band discontinuity of collectors displacement from the side of injection point.
