摘要

Composition of hydroxyethyl cellulose hydrated for making it more viscous a brine, the activation of the hydroxyethyl cellulose, in order to obtain such a composition, and treatment fluid oil well containing the composition. / p & & p & in order to obtain the composition, it is subject to a liquid oleaginous and a compatibilizing agent in order to form a viscous suspension, it incorporates an aqueous solution of a mineral salt having an exothermic heat of dissolution, then the mixture the hydroxyethyl cellulose, in order to form a composition pourable and viscous, which is hydrate in brines, the density is at least the same has 1,619kglitre. / p & & p & application: completion fluids or repackaging of wells oil.
