FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry and can be used for increasing oil and gas recovery of the formation. According to the method, charges are placed in production and injection wells. Central well is selected so that all subsequent treated wells are located along the line of round or elliptical spiral. Processed wells can be located around central well in nodes of mesh polygonal arrangement of wells. Charges of pressure generators are inflamed in two and more wells located in opposite sides relative to central well on polygon perimeter, which is closest to central well, and then in wells located on perimeter of next polygon around central well, with displacement from central well to periphery formation. Charges in wells are successively spirally from center to periphery or synchronously two and more wells located in opposite sides from central well.
EFFECT: long-term increase of oil extraction of treated reservoir volume.
