FIELD: oil and gas industry.
SUBSTANCE: method involves oil extraction of through production wells, change-over of some production wells to injection wells, formation of rows of injection wells perpendicular to direction of natural fracturing and pumping of working agent through injection wells. According to the invention rows of injection wells located perpendicular to direction of natural fracturing are formed of production wells changed over to injection wells. Between rows of injection wells located perpendicular to direction of natural fracturing there arranged are 2 to 5 rows of production wells which are located perpendicular to direction of natural fracturing too. Additional production wells are arranged in rows of injection wells between existing wells. Before production wells are changed over to injection ones, they are operated in forced mode until saturation pressure is achieved in each well.
EFFECT: increasing oil recovery of deposit.
