Beschreibung
Zusammenfassung:	oil producing industry, particularly, methods of development of nonuniform oil formations with use of gelling composition. SUBSTANCE: method includes successive injection of aqueous solutions of polymer, alkali and alumino-containing reagent through injection well. Alumino-containing reagent is used in the form of aluminum hydroxychloride with addition of 0.5 wt.% of corrosion inhibitor. In this case, polymer, alkali and aluminum hydroxychloride are used in ratio of 1:100:100. EFFECT: higher efficiency of development of oil deposits under conditions of formations nonuniform in permeability at late stage of their development. 2 cl, 1 tbl, 1 ex
