摘要：This invention relates to a composition comprising a mixture of a brine and aliquid oil, and (A) an emulsifying amount of (i) at least one reaction product of a
hydrocarbyl-substituted succinic acylating agent, and at least one of (a) ammonia, (b) analcohol, or (c) an amine, or at least one salt of the reaction product; or (ii) at least onereaction product of a hydroxyaromatic compound, an aldehyde, and an amine, and (B) atleast one surfactant selected from the group consisting of a polyoxyalkylene amine, apolyoxyalkylene amide, a polyoxyalkylene alcohol, a polyoxyalkylene phenol, a
polyoxyalkylene ester, a fatty acid salt, an amine or an alkaline earth or transition metalsulfonate, or a reaction product or a hydroxyamine or a polyalkylenepolyamine with anacylating agent selected from the group consisting of a fatty monocarboxylic acylatingagents, a dicarboxylic acylating agent other than a succinic acylating agent, and atricarboxylic acylating agent. The compositions of the present invention have beneficialemulsion and viscosity properties. These compositions are useful in drilling, working and
completing well bore holes. The compositions of the present invention have beneficialviscosity, pumping and suspension properties. These compositions are stable. Thesurfactants of the compositions act as wetting agents for barites and organophilic clays.The surfactants may also act as an emulsifier as well as a wetting agent.
