FIELD: oil extractive industry. ^ SUBSTANCE: reagent contains bitumen emulsion in form of bitumen dispersion in water solution and surfactants. As said dispersion thin dispersion of bitumen with melting temperature of 35-135C in 1% water solution of NaOH or HCl, and surfactants are - cation-active, anion-active or non-ionogenic are used as emulsifier, and additionally calcium chlorine, with following ratio of components in percents of mass: said bitumen - 30.0-80.0 percents, said emulsifier - 0.15-5.0, calcium chlorine - 0.05-0.5, 1% water solution of NaOH or HCl - the rest. Method of oil bed treatment including pumping of said bitumen-containing reagent into the bed or its mixture with hydrocarbon dissolvent and/or mineral powder, as hydrocarbon dissolvent oil is used or cubic remains of ethylbenzol and styrene manufacture - "Korae" resin, and as mineral powder - bentonitic clay. ^ EFFECT: higher oil extraction productiveness of beds. ^ 2 cl, 3 ex, 3 tbl |
