Способ обработки призабойной зоны нагнетательной скважины, включающий закачку в скважину аэрированного раствора поверхностно-активного вещества в воде и последующее освоение скважины, отличающийся тем, что перед закачкой в скважину раствора поверхностно-активного вещества в воде его аэрацию осуществляют с кратностью не менее 4,5 при пластовых условиях, а закачку в призабойную зону - под давлением не ниже разницы между величинами 1,7 Pп л и гидростатическим давлением аэрированного раствора, где Pп л - пластовое давление.A method of processing a bottom-hole zone of an injection well, comprising injecting an aerated solution of a surfactant in water into a well and then developing a well, characterized in that before a solution of a surfactant in water is injected into a well, its aeration is carried out with a multiplicity of at least 4.5 at reservoir conditions, and injection into the bottom-hole zone - under pressure not lower than the difference between the values of 1.7 P p l and the hydrostatic pressure of the aerated solution, where P p l - reservoir pressure.
