Abstract

Method of treatment of nonuniform permeable productive strata consists in sequential pumping-in to the bed water micellar solution, polymer solution and mineralized water. The 0.5-3 % solution of gamma-irradiated polyacrylamide is used as polymer solution, at pumping a portion of this solution to the stratum one continues at the same time pumping-in the water micellar solution, and after the end of pumping-in the solution of polymer to the stratum, one more portion of the named micellar solution is additionally pumped in to the bed. As the water micellar solution one uses 2-8 % on petroleum sulfonates water micellar solution. This method provides increase of the displacement coefficient for the residual oil.
