This invention relates to a composition comprising a mixture of a brine and a liquid 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) an alcohol, or (c) an amine, or at least one salt of the reaction product; or (ii) at least one reaction product of a hydroxyaromatic compound, an aldehyde, and an amine, and (B) at least one surfactant selected from the group consisting of a polyoxyalkylene amine, a polyoxyalkylene amide, a polyoxyalkylene alcohol, a polyoxyalkylene phenol, a polyoxyalkylene ester, a fatty acid salt, an amine or an alkaline earth or transition metal sulfonate, or a reaction product or a hydroxyamine or a polyalkylenepolyamine with an acylating agent selected from the group consisting of a fatty monocarboxylic acylating agents, a dicarboxylic acylating agent other than a succinic acylating agent, and a tricarboxylic acylating agent. The compositions of the present invention have beneficial emulsion and viscosity properties. These compositions are useful in drilling, working and completing well bore holes. The compositions of the present invention have beneficial viscosity, pumping and suspension properties. These compositions are stable. The surfactants 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.
本发明涉及一种组合物,该组合物包括盐水和液体油的混合物,以及(A)以下物质的乳化量:(i) 至少一种烃基取代的琥珀酰化剂与(a)氨、(b)醇或(c)胺中至少一种的反应产物,或该反应产物的至少一种盐;或 (ii) 至少一种羟基芳香族化合物、醛和胺的反应产物,以及 (B) 至少一种表面活性剂,该表面活性剂选自由聚氧亚烷基胺、聚氧亚烷基酰胺、聚氧亚烷基醇、聚氧亚烷基酚、聚氧亚烷基酯、脂肪酸盐组成的组、胺或碱土金属或过渡金属磺酸盐,或羟胺或聚亚烷基多胺与酰化剂的反应产物,酰化剂选自脂肪一羧酸酰化剂、二羧酸酰化剂(琥珀酸酰化剂除外)和三羧酸酰化剂组成的组。本发明的组合物具有良好的乳化和粘度特性。这些组合物可用于钻井、修井和完井。本发明的组合物具有良好的粘度、泵送和悬浮特性。这些组合物具有稳定性。组合物中的表面活性剂可作为重晶石和亲有机粘土的润湿剂。表面活性剂还可用作乳化剂和润湿剂。
