FIELD: gas industry.
SUBSTANCE: water-repellent compositions for limiting water inflows in gas wells at the initial stage of water manifestation. Water-repellent composition contains 2-4 wt. % silicate reagent “Polyekosil-N”, 0.5-1.5 wt. % water repellent “GKZH-11N”, 0.4-0.6 wt. % lignosulfonate “LSTP”, 0.1-0.3 wt. % pine rosin, 0.05-0.15 wt. % urotropin, 0.1-0.3 wt. % borax, water - the rest.
EFFECT: increasing the insulating ability of the water-repellent composition to limit water inflows and increase the overhaul period of wells.
