FIELD: oil and gas production. SUBSTANCE: homogeneous fluid capable to be split into a solvent for liquid hydrocarbons and surface active liquid under formation thermobaric conditions is pumped in into formation. As such a fluid, 15-25% ammonium hydrocarbonate aqueous solution is used prepared by interaction of carbon dioxide originated from produced gas with aqueous ammonia. Fluid is stabilized against action of calcium and sodium chlorides with addition of 10-15% ammonium chloride solution. EFFECT: increased stability of injection fluid. 3 cl
