FIELD: crude oil production from stratum at any stage of water flowing during oil-fields development to intensify operation of producing wells and to increase running oil recovery. SUBSTANCE: aim is to increase thermal stability of composition and its crude oil displacement capability, to decrease chemical reactants usage. composition for crude oil production has following components: hydrocarbon solvent (10.0 - 20.0 mass %), emulsifier "Neftenol НЗ" (0.3 - 3.0 mass %), "ГКЖ-10" or "ГКЖ-11" stabilizer (0.1 - 1.0 mas %) and water - balance. EFFECT: increased running oil recovery. 2 cl, 1 tbl |
