FIELD: oil and gas industry.
SUBSTANCE: compound-action composition for treatment of bottom-hole zone of gas well contains 70% of methanol water solution and mixture of surface active substances - SAS: non-ionic - OP-10 and anionic sulphanole at their ratio of 4:1 respectively, where the quantity of the above mixture is chosen as per the specified formula.
EFFECT: creation of compound-action composition for treatment of bottom-hole zone of gas well, which prevents foaming of pumped medium at its being supplied to bottom hole and hydrating along the shaft of gas well and in ground equipment when the liquid is carried over to surface and providing high efficiency for removing high-mineralised waters in presence of gas and gas condensate from bottom holes of low temperature gas wells.
