FIELD: chemistry.
SUBSTANCE: present invention relates to gas and gas condensate production, namely to chemicals for removal of gas well and condensate well fluid, containing highly mineralised produced water (total minerals 50-200 g/l) and up to 50% of hydrocarbon condensate. Process blend for removal of gas well and condensate well fluid, containing highly mineralised produced water and gas condensate, containing non-ionic surfactant - NIS polyethylene glycol - 4000, also containing NIS syntanol "АЛМ-10", and anionic surfactant sodium dodecylsulfate, with the following ratio, wt %: polyethylene glycol -4000 70-80, syntanol "АЛМ-10" - 5-10, sodium dodecylsulfate 15-25.
EFFECT: efficient removal of formation fluid, containing highly mineralised produced water and hydrocarbon condensate from gas and gas condensate wells using a dedicated surfactant.
