FIELD: oil production industry, working of oil and oil and gas fields including several horizons of collectors of various types. SUBSTANCE: optimum seam pressure for extraction of products from each productive horizon is determined before start of working of oil field. Base horizon carrying maximum stock of oil is selected. Then production wells are set in operation under optimum seam pressure for base horizon. Seam pressures in production wells for the rest of horizons are determined by seam pressure in base horizon and are computed with correction for hydraulic coupling between them over shaft of well. EFFECT: reduced operational expenses, increased current extraction of oil, raised coefficient of extraction and enhanced oil output in case of joint working of several horizons. 5 dwg, 4 tbl
