FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to production of gas and gas condensate, namely to chemical reagents for maintaining stable operation of water-flooded gas and gas condensate wells in conditions of falling production. Surfactant composition for maintaining stable operation of water-flooded gas and gas condensate wells under conditions of falling production consists of a mixture, wt. %: amphoteric surfactant Alkylamidopropylbetaine B-4 70.0, anion-active surfactant Sulphanol of bleached brand 25.0, complexing compound Trilon B 5.0.
EFFECT: technical result is higher efficiency of removal from wells of formation fluid and, consequently, maintenance of stable operation of gas and gas condensate wells in conditions of falling production of surfactant use technology.
