FIELD: oil production. SUBSTANCE: while developing oil pool by flooding aqueous solution of partially hydrolyzed polyacrylamide and clay suspension in equivalent volumes are injected in turn through injection hole. Water in the amount of 5-10% of volume of pumped aqueous solution of partially hydrolyzed polyacrylamide is pumped between these volumes. Technological curing in the course of 8-60 h is then performed. Next pumping of working agent is conducted under increased pressure corresponding to take-in characteristics of well before treatment. Oil is removed through production wells. EFFECT: improved efficiency of process.
