摘要

FIELD: oil and gas industry.SUBSTANCE: according to the method, when oil deposit is being developed, working fluid is pumped through injection wells and product is extracted through vertical and horizontal production wells with an uprising shaft. Horizontal wells with the uprising shaft are made of one cluster in the form of a fan; lower part of each well is arranged at the distance of 7-10 m above the boundary between oil saturation zone and residual oil saturation; wells are made with an open shaft in productive formation zone.EFFECT: increasing oil recovery of deposit.1 ex, 2 dwg
