FIELD: oil and gas production. SUBSTANCE: effective development of permeability-nonuniform watered oil strata includes alternating pumping in of aqueous solution of a partially hydrolyzed polyacrylamide and clay suspension followed by affecting the bed with aqueous solution of a chemical reagent. The latter consists of (in wt %): petroleum or synthetic sulfonates with equivalent weight 330 to 580, 0.25-7; alkylphenols with oxyethylation degree 8-16, 0.25-7; a solvent, 0.25-2.75; water, the balance. EFFECT: increased oil production. 2 tbl
