| description | The invention is referred to the oil production industry and in particular to oil production compositions based on hydrocarbon and/or oil solutions of surfactants which possess ultra low interface tension on the oil-water boundary that determines their ability to independently form stable oil in water type emulsions and show certain oil washing properties at the time of injection into the reservoir. Proposed composition for oil production contains a small number of ingredients. It is easy to prepare, forms kinetically and aggregately stable "oil in water" micro emulsion, as a result of slow adsorption the surfactant on the rock has a good oil washing property and the process is economical. The content of regulator-solvent in the developed composition of 15-25% of mass allows not only to effectively dissolve the surfactant initially in the regulator but also provide required colloid dispersion (close to molecular) state of asphaltene-resin components in oil which assists the formation of associates from surfactant molecules and polar oil components and slows down surfactant adsorption i.e. allows to wash a larger oil volume from the pore volume of the reservoir. 2 tables. |
