FIELD: oil production industry. SUBSTANCE: this can be used for increasing efficiency of oil recovery from beds, and also it can be used in drilling oil wells. According to method, addition to water injected into oil bed is obtained by fulfilling following operation: polyacrylamide powder is subjected to treatment by gas mixture which contains 10-15% of oxygen at temperature of 100-120 C during 1-20 h. Application of aforesaid method improves rheological properties and enhances oil recovery from bed at displacing oil from bed. EFFECT: higher efficiency. 1 tbl, 3 ex
