FIELD: gas production.
SUBSTANCE: composition for removal of incoming formation fluid from wells and maintenance of stable operation of wells of gas deposits, which have passed to the final stage of development, characterized by a drop in formation pressure, contains a nonionic surfactant – neonol “АФ” 9-12, a zwitterionic surfactant – cocamidopropyl betaine, an anion-active surfactant – sodium alpha-olefin sulphonate and fresh water at a ratio of neonol “АФ” of 9-12 : cocamidopropyl betaine : sodium alpha-olefin sulphonate : fresh water, respectively, wt.%: 2:4:4:90, or 4:4:2:90, or 4:2:4:90.
EFFECT: providing effective removal of incoming formation fluid from wells and maintaining stable operation of wells of gas fields, which have passed to the final stage of development and are characterized by drop of formation pressure.
