FIELD: gas industry.
SUBSTANCE: invention relates to gas production industry, in particular to compositions used for isolation of water influx in gas and gas condensate wells, including those with subhorizontal shaft end. Composition for isolation of water influx in gas wells is characterized by the fact that it contains a gel formation regulator – citric acid or acid reagent “IsoSmart-M”, “Sumix” gelling agent, an acid thickener containing oxalic acid and an adhesive additive – potassium bromate or “IsoSmart-S” acid reagent, with the following ratio of ingredients, wt. %: citric acid or acid reagent “IsoSmart-M” 3-8, gelling agent “Sumix” 4-10, oxalic acid 1.0-3.5, potassium bromate 0.02-0.30 or acid reagent “IsoSmart-S” 2-6, water – the rest.
EFFECT: high insulating capacity of the composition and high technological effectiveness of its preparation.
