FIELD: gas production.
SUBSTANCE: composition of liquid surfactants for maintaining stable operation of watered gas wells in conditions of declining production of an oil and gas condensate field contains the following, wt.%: ethylene glycol ethers of alcohols C12-18 0.1-5; 17-(4-nonylphenoxy)-3,6,9,12,15-pentaoxaheptadecan-1-ol 0.1-10; sodium alpha-olefin-sulphonate 0.001-20; alkylamidopropyl betaine 0.001-40; freezing point depressants of the composition and hydrate formation inhibitors are ethylene glycol 0.001-50 and a composition based on polyalcohols 30-70.
EFFECT: increased efficiency of formation fluid removal from wells, maintenance of stable operation of gas wells in conditions of decreasing production.
