FIELD: oil and gas industries. SUBSTANCE: process can find use in various technological operations, specifically, for perforation of wells, insulation of oil ,gas, water manifestations, plugging, etc. Technical result of invention lies in increase of efficiency of preservation of collecting properties of face zone of pool of production well with utilization of solutions of mineral salts as key means for action on pool. In correspondence with process shaft of well is injected with aqueous solution of concentrated sylvanite ore with inhibitor of precipitation formation. In this case aqueous solution is placed either opposite to productive pool or above seam roof with formation of hydraulic column above roof of productive pool. EFFECT: increased efficiency of preservation of collecting properties of face zone of production well. 13 cl
