Abstract
FIELD: oil and gas production. SUBSTANCE: to stabilize gel formation time in insulating product containing organosilicon compound, to basic hardener, mineralized stratum water as cohardener is added. The additive makes also it possible to reduce consumption of basic hardener (hydrochloric acid). EFFECT: enhanced efficiency of gel formation.

Предлагаемый состав относится к нефтегазодобывающей отрасли и используется для изоляции водопритока в скважине. Для стабилизации времени гелеобразования (при разных температурах) продукта 119 - 296Т, содержащего кремнийорганическое соединение, предложено к основному отвердителю добавлять соотвердитель - минерализованную пластовую воду. Кроме стабилизации времени гелеобразования, эта добавка позволяет экономить основной отвердитель - соляную кислоту.The proposed composition relates to the oil and gas industry and is used to isolate water inflow in the well. To stabilize the gelation time (at different temperatures) of product 119-296T containing an organosilicon compound, it was proposed to add a hardener - mineralized formation water to the main hardener. In addition to stabilizing the gelation time, this additive saves the main hardener - hydrochloric acid.
