METHOD OF WORKING OF OIL DEPOSIT

摘要

oil industry. SUBSTANCE: invention refers to working of oil deposits with inhomogeneous pools with conducting of insulation operations to level profile of intake capability of injection holes and limiting of water inflow to production oil wells. Method of working of oil deposit includes pumping of aqueous solution of sodium silicate and of structure-forming reagent-rock carrying zeolite treated in advance with sulfuric or hydrochloric acids into pool and curing. Pumping of above-mentioned aqueous solution of sodium silicate and zeolite-carrying rock can be executed simultaneously or sequentially. EFFECT: increased efficiency of working of oil deposit and enhanced oil recovery. 1 cl, 2 tbl
