FIELD: gas production.
SUBSTANCE:The invention relates to gas and gas condensate extraction. Solid foaming agent for removing reservoir fluid for gas and gas condensate wells contains, %: oxyethylated surface-active substance Lutensol AT 25 or AT 50 - 40-80, polyvinylpyrrolydone 20- 60.
EFFECT: increased reservoir liquid removal efficiency from wells, where the well production contains stratum water with salts amount up to 200g/l at the temperature up to 72°C and the concentration of carbohydrate condensate up to 50 % of volume.
