METHOD OF DEVELOPMENT OF OIL FORMATION Russian patent published in 2001 - IPC

Abstract RU 2172397 C2

FIELD: oil producing industry, particularly, methods of oil formation development by polymer flooding. SUBSTANCE: method includes injection of aqueous solution of polymer with concentration of 0.10-0.20% and water into injected wells. Polymer solution is injected by a few portions with their alternating with water injection up to attaining concentration of polymer solution in formation within 0.1-0.001%. EFFECT: higher efficiency of polymer flooding due to increased resistance of polymer solutions to mechanical and salt destruction. 3 tbl
