FIELD: oil production industry. SUBSTANCE: treatment of down-hole zone is performed when down-hole pressure is below saturation pressure in conditions of gas emittance and accumulation in down-hole zone of non-uniform oil beds. Applied compound penetrates into difficult intervals due to its viscous-resilient properties. Compound has following relation of components, mass %: polyacrylamide 0.02-0.04, sulphonol 0.005-0.1, water - the balance. EFFECT: high efficiency. 1 tbl
