FIELD: oil and gas industry. ^ SUBSTANCE: above described formation is brought into contact with fluid medium, where fluid medium is at least the medium which at least partially dissolves or at least partially displaces the brine in the above formation, and subsequently, the above formation is brought into contact with composition including the following: non-ionic fluorated polymer surface-active substance - NFPSAS, which contains at least one bivalent unit represented with structural formulae, and solvent; at that, when composition is brought into contact with the above formation, the above mentioned NFPSAS has turbidity point which is higher than the temperature of the above formation. Invention is developed in dependent claims. ^ EFFECT: increasing production rate of wells, where brine or gas condensate is present. ^ 25 cl, 3 ex, 20 tbl, 3 dwg |
