FIELD: gas industry.
SUBSTANCE: invention relates to gas production. Surfactant mixture for foaming and removal of liquid formation fluid from gas condensate wells with abnormally high formation temperatures contains fresh water, as an anionic surfactant sulphonol, as a non-ionic surfactant alkyldimethylamine oxide, emulsifier - polyethylene glycol and softener - sodium silicate with the following ratios of sulphonol:sodium silicate:polyethylene glycol:alkyldimethylamine oxide:fresh water, wt.%: 3:0.1:0.9:6:90, or 4:0.1:0.9:5:90, or 5:0.1:0.9:4:90, or 6:0.1:0.9:3:90, or 7:0.1:0.9:2:90, or 8:0.1:0.9:1:90, or 3:0.1:6:0.9:90, or 4:0.1:5:0.9:90, or 5:0.1:4:0.9:90, or 6:0.1:3:0.9:90, or 7:0.1:2:0.9:90, or 8:0.1:1:0.9:90, or 3:0.5:0.5:6:90, or 4:0.5:0.5:5:90, or 5:0.5:0.5:4:90, or 6:0.5:0.5:4:90, or 7:0.5:0.5:2:90, or 8:0.5:0.5:1:90, or 3:0.5:6:0.5:90, or 4:0.5:5:0.5:90, or 5:0.5:4:0.5:90, or 6:0.5:3:0.5:90, or 7:0.5:2:0.5:90, or 8:0.5:1:0.5:90, or 3.8:0.1:0.1:6:90, or 4.8:0.1:0.1:5:90, or 5.8:0.1:0.1:4:90, or 6.8:0.1:0.1:3:90, or 7.8:0.1:0.1:2:90, or 8.8:0.1:0.1:1:90, or 3.8:0.1:6:0.1:90, or 4.8:0.1:5:0.1:90, or 5.8:0.1:4:0.1:90, or 6.8:0.1:3:0.1:90, or 7.8:0.1:2:0.1:90, or 8.8:0.1:1:0.1:90, or 3:0.9:0.1:6:90, or 4:0.9:0.1:5:90, or 5:0.9:0.1:4:90, or 6:0.9:0.1:3:90, or 7:0.9:0.1:2:90, or 8:0.9:0.1:1:90.
EFFECT: providing effective foaming and removal of liquid formation fluid from gas condensate wells with abnormally high formation temperatures.
