Abstract RU 2009159 C1

FIELD: repair and punching works in the well. SUBSTANCE: reagent is produced by roasting limestone, slaking calcium oxide followed by interaction of calcium oxide with ammonium liquor. The product so obtained is thermally treated in a spraying drier with a gas flow in a temperature range of 480-650 C. The final product is a light pulverized powder with a good water solubility and without tendency to caking for 4-4.5 months. The suppression liquid based on the reagent gives rise to the coefficient of recovery of the stratum productivity. EFFECT: enhanced productivity of the stratum recovery.
