FIELD: oil-and-gas production.
SUBSTANCE: method is implemented on the basis of waterflooding with application of horizontal producing wells and vertical pressure wells. According to the invention, vertical pressure wells are located in corners of five-point element. In those there are opened by perforation one third part in bottom part of productive stratum. Horizontal producing well is located nearby the roof of productive stratum parallel to two sides of square in the centre of five-point element with length of bore equal to one third of distance between pressure well bottom.
EFFECT: effectiveness increase of development of oil pool at presence in productive cut of supercollector.
