FIELD: oil and gas production.
SUBSTANCE: procedure for development of non-uniform reservoir consists in pumping water solution into reservoir. Solution contains wt %: poly-acryl-amide 0.3-1.0, chromium acetate 0.03-0.1, zinc oxide 0.03-0.1. Also, poly-acryl-amide and chromium acetate are mixed at ratio close to 10:1. Produced water solution is forced through into reservoir with water by volume exceeding volume of string, through which water is pumped, at not less, than 0.5 m3, with successive process conditioning for period of gelation of water solution.
EFFECT: raised efficiency of non-uniform reservoir development and reduced power expenditures.
