FIELD: oil and gas extracting industry. SUBSTANCE: method includes pumping of water solution of carbonate with addition of spirits into the well. As a carbonate, sodium carbonate is used at concentration in water solution of 5-30% percents of mass, and as spirits, spirits with amount of carbon atoms C1-C17 and concentration of 0.05-2% of mass, with their amount of up to 25% of amount of said water solution of sodium carbonate. EFFECT: stable isolating screen with increased duration of operation due to forming of calcite crystals of marmoreal type.
