FIELD: oil production industry. SUBSTANCE: this relates to development of hydrocarbon deposits with utilization of gases produced by gasification of coal seams. According to method, undertaken is combined development of two deposits. Injected into oil bed is steam, and it is delivered through injection well. Prior to delivering steam into injection well, preliminarily injected is saturated solution of one of carbonate or bicarbonate salts of alkali metals or ammonium. Volume of solution is calculated according to formula which takes accounts of relations which are determined experimentally. Recovery of product is effected through producing well. Application of aforesaid method, allows for reduction of corrosive activity of recovered product, and for reducing stability of water-oil emulsion. EFFECT: higher efficiency. 1 tbl, 1 dwg
