Abstract

FIELD: petroleum production industry. SUBSTANCE: gelatinizing compound uses, as acrylic polymer waste of fiber or fabrics of polyacrylonitrile hydrolyzed in alkali, sodium silicate and additionally - calcium chloride or mineralized stratal water at the following relation of component, mass percent: filer or fabrics of polyacrylonitrile hydrolyzed in alkali - 1.0-5.0; sodium silicate - 0.3-3.0; calcium chloride - 2.0-5.0; water - the rest. EFFECT: enhanced yield of petroleum from producing strata, non-uniform in permeability, based on acrylic polymer, reduced price of compound.
