1. Способ подачи реагентов в фонтанирующие газоконденсатные скважины, отличающийся тем, что время продвижения реагента по кольцевому межтрубному пространству не должно быть менее времени образования защитной пленки на внутренней поверхности обсадных и на наружной поверхности насосно-компрессорных труб, а время прохождения реагента по насосно-компрессорным трубам совместно с выносимой с забоя скважины продукцией пласта не должно быть менее времени образования защитной пленки на их внутренней поверхности, причем время продвижения реагента по кольцевому пространству регулируют путем закачки продавочной жидкости, а время продвижения реагента по насосно-компрессорным трубам регулируют объемом отбора продукции пласта.1. The method of supplying reagents to flowing gas condensate wells, characterized in that the time of advancement of the reagent along the annular annular space should not be less than the time of formation of the protective film on the inner surface of the casing and on the outer surface of the tubing, and the passage of the reagent through the tubing the pipes together with the production of the formation carried out from the bottom of the well should not be less than the time of formation of a protective film on their inner surface, and the time of advancement of Gent in the annular space is regulated by injection of squeezing fluid, and the time of advancement of the reagent through the tubing is controlled by the volume of production of the formation. 2. Способ по п. 1, отличающийся тем, что удельный вес жидкости (смесь продукции скважины и реагента) не должен превышать величины:
Figure 00000001

где γ- удельный вес жидкости, кг/дм3;
Pпл - пластовое давление, кгс/см2;
H - расстояние от устья скважины до верхних отверстий интервала перфорации, м.2. The method according to p. 1, characterized in that the specific gravity of the fluid (a mixture of well products and reagent) should not exceed the value:
Figure 00000001

where γ is the specific gravity of the liquid, kg / dm 3 ;
P PL - reservoir pressure, kgf / cm 2 ;
H is the distance from the wellhead to the upper holes of the perforation interval, m
