发明名称 METHOD OF PRODUCTION OF ADDITIVE TO WATER INJECTED INTO OIL FORMATION
摘要 oil recovery, more specifically, methods of production of additives to water injected into oil formation for increase of recovery efficiency of oil formations. SUBSTANCE: method includes treatment of powdery polyacrylamide with ionizing radiation and subsequent treatment of radiated polyacrylamide with water in amount of 10-30% of polyacrylamide weight. Treatment with ionizing radiation is carried out to obtain absorbed radiation dose of 0.1-1.0 Mrad. Treatments with radiation and water are carried out at atmospheric conditions. EFFECT: improved stability and, as a result, performance characteristics of additive due to protection of polymer from destruction, simplified method. 3 cl, 2 tbl, 2 ex
