FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to gas industry and can be used to carry accumulated drop-type fluid on bottom in process of gas well operation or repair, operation of which is complicated by availability of hydrated-ice plugs in the well shaft, especially in conditions of abnormally low formation pressures. Composition of surfactants for gas wells, containing, wt. %: surfactant OP, Sulfanol 40 % aqueous solution, Trilon B, methyl alcohol, wt. %: OD 27.5÷37.5 %; Sulfanol 40 % aqueous solution 20÷10; Trilon B up to 2.5 %; Aqueous solution of methyl alcohol is the rest.
EFFECT: use of the disclosed solution will allow increasing gas production from gas wells, as well as reducing operating costs during gas production and reducing the number of well blowouts.
