FIELD: gas industry.
SUBSTANCE: present invention relates to the field of gas production and gas condensate, namely to chemical reagents for removing liquid from wells of gas fields and gas condensate fields, which contain highly mineralized formation water (total mineralization up to 300 g / l) and gas condensate (up to 50%). Technological mixture for the removal of reservoir fluid from gas and gas condensate wells, containing highly mineralized formation water and gas condensate, containing non-ionic surfactant OC-20 Preparation, additionally contains an anionic Sulfoethoxylate surfactant of fatty alcohols and Polycell CMC, at the following ratio,% by weight: OC-20 70-80 preparation, Sulfoethoxylate of fatty alcohols 15-25, Polycell CMC 3-5.
EFFECT: technical result is to ensure effective removal of reservoir fluid containing highly mineralized formation water and gas condensate.
