Abstract

FIELD: oil production industry, compositions for increasing stratum oil recovery in process of water encroached wells treatment with end-to-end water flooding. SUBSTANCE: aim is to increase stratums oil recovery and insulation of water inflow to oil wells due to increased stability of formed in stratum gel. Composition has aluminum salts, carbamide, polyacrylamide and water with following ratio of components, mass %: polyacrylamide - 0.5 - 2.5; aluminum chloride - 0.4 - 17.0; carbamide - 1.5 - 30.0; water - balance. EFFECT: increased oil production.
