COMPOSITION FOR SEALING INFLUX OF WATER INTO WELL Russian patent published in 2012 - IPC C09K8/504 

FIELD: chemistry.

SUBSTANCE: invention relates to oil industry, particularly to a composition for sealing influx of water into a well. The composition for sealing influx of water into a well contains an organosilicon compound - product 119-296, a curing agent - titanium (IV) chloride, polyglycols, Devonian stratal water and oligophenyl ethoxy siloxane (OPES) in the following ratio, wt %: product 119-296 40.5-61.5, OPES 15.0-25.0, TiCl₄ 3.5-4.5, polyglycols 20.0-30.0, wherein the Devonian stratal water is taken in ratio of 1:1 to the weight of the rest of the reagents of the composition.

EFFECT: high efficiency of sealing water influx owing to higher strength of the composition, longer inter-repair period of the well, which enables to save repair materials 1,5-fold.
