FIELD: oil production, particularly oil production from wells adapted to extract oil from bed having non-uniform permeability and comprising super conductors or cracks in bed section.
SUBSTANCE: method involves injecting aqueous solution of polymer and multivalent cation salt in oil bed with the use of gel particle dispersion. Gel particle dispersion in aqueous polymer solution is injected as the first plug. Then aqueous solution of polymer and multivalent cation salt is injected as the second plug. Forced fluid extraction may be additionally carried out.
EFFECT: increased oil recovery and decreased water content in oil well product, increased efficiency of deposit development.
