摘要

the invention relates to mixtures of surfactants containing the hydrocarbon part (r1), (r2) - ch - CH2 - at least three different ionic surfactant of general formula (i);in which r1, r2, a0, k, x, y, a, b, m have the values specified in the description, and the formula of the invention.the invention further relates to their use and to compositions containing a mixture of surfactants and water, as well as the way of oil extraction by u0437u0430u0432u043eu0434u043du0435u043du0438u044f u043cu0438u043au0440u043eu044du043cu0443u043bu044cu0441u0438u044fu043cu0438 type u0432u0438u043du0437u043eu0440u0430 iii, in which the surfactant water pump through u043du0430u0433u043du0435u0442u0430u0442u0435u043bu044cu043du0443u044e well in oil field, and from the field through both with u043au0432u0430u0436u0438u043du0443 have crude oil.
