Beschreibung
Zusammenfassung:	FIELD: petroleum extracting industry. SUBSTANCE: method includes pumping water pulp of crosslinking material - gypsum and water solution of silicate of univalent cation. As gypsum chemical gypsum is used - phosphogypsum, fluorinegypsum, borongypsum, magnesium gypsum, hydrolytic gypsum. As univalent cation sodium, potassium, lithium may be used. Said pulp comprises chemical gypsum with concentration of 2.1-7.5%. Said water solution is used with concentration of 21-50%. Pumping of said pulp and solution can be done synchronously or consecutively. Said pulp my contain additive filler - bentonite argil, wooden flour, quartz sand at following relation of chemical gypsum : filler 1 - 10:1. EFFECT: receiving of stable volumetric isolation material, effective against layer water or pumping water break-through, and due to that, possible taking of stagnant and low-drainable layer areas into development. 2 cl, 4 tbl
