FIELD: chemistry.
SUBSTANCE: invention relates to oil and gas extraction industry, particularly to compositions used to seal influx of water into a well, including a high temperature well. The composition for sealing influx of water into a well contains an alkoxy-containing organosilicon compound and butyl ether of ortho-titanic acid. The alkoxy-containing organosilicon compound contained in the composition is an AGM-9 product, and the butyl ether of ortho-titanic acid is polybutoxytitanium, with the following ratio of components, vol. %: AGM-9 product 0.5-5.0, polybutoxytitanium 95.0-99.5.
EFFECT: high corrosion resistance and low permeability of water saturated reservoirs, creation of a reliable insulating shield with high heat resistance which facilitates use of the composition in a wide temperature range.
