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, magnesium oxide 0.015-0.07, and water - the rest. 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 in 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 development of non-uniform reservoir due to increased strength of gel-forming water solutions of polymer and reduced power expenditures owing to reduced induction period of gel-forming.
