FIELD: chemistry.
SUBSTANCE: invention relates to oil and gas industry, particularly compositions for sealing influx of water into oil wells. The composition contains an organosilicon compound, a polar solvent, filler and a catalyst. The organosilicon compound used is an ortho-silicate. The catalyst used is aqueous hydrochloric acid solution. The filler used is an aqueous dispersion of a sodium salt of carboxymethyl cellulose or an aqueous dispersion of polyvinyl acetate. Said components of the composition are taken in the following ratios, pts.wt: organosilicon compound - 100-150, polar solvent - 10-20, catalyst - 5-20, filler - 100-150.
EFFECT: providing reliable plugging of a waterlogged oil reservoir using a water-filled water-proofing composition with controlled hardening time and high strength properties of the plugging material.
