FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to gas production, namely, to solid chemical reagents for foaming and removal of liquid from wells of gas fields. Solid foaming composition for foaming and removal of formation gas deposits from low-yield gas wells and maintenance of stable operation of gas wells, containing nonionic surfactant preparation OS-20, additionally contains an anionic surfactant sodium dodecyl sulphate, sulfonol powder and a complexing compound Trilon B at the following ratio, wt. %: preparation OS-20 65, sodium dodecylsulphate 15, sulfonol powder 15, Trilon B 5.
EFFECT: technical result is effective foaming and removal of liquid to maintain stable operation of low-yield gas wells.
