FIELD: oil industry.
SUBSTANCE: method includes prior geophysical research, pumping buffers of argillaceous dispersion, polymer and fresh water buffer through force well, buffer of argillaceous dispersion and polymer in form of its water solution are forced concurrently or serially, concurrently or after that alkali reagent solution is fed, fresh water buffer is pumped, then - solution of salts of bivalent and trivalent metals, or buffer of mineralized drain water, then all reagents are forced by drain water, relation of volume of alkali reagent solution and volume of argillaceous dispersion and water solution of polymer is selected on basis of geophysical research dependently on distribution of penetrability along thickness in accordance to penetrability variation coefficient, and it is 2:1 - 4:1.
EFFECT: higher oil yield.
