Beschreibung
Zusammenfassung:	oil and gas industry, insulation operations in wells. SUBSTANCE: compound for insulation of stratal waters in oil and gas wells includes cement, acrylic water-swelled polymer and water. Aqueous solution of polyacrylamide with concentration 0.5-1.0 per cent by mass irradiated by dose 0f 5-10 KGy of gamma radiation is used in the capacity of water-swelled polymer. Compound has the following proportion of components, per cent by mass: cement 60.0-65.0; aqueous solution of polyacrylamide 0.5-1.0; water being the balance. EFFECT: formation of water-tight screen in path of water coming into well. 1 tbl
