    • This invention relates to a composition comprising a mixture of a brine and a liquid hydrocarbon, and (A) a viscosity increasing amount of at least one ester of a carboxy-containing interpolymer or salt thereof wherein the interpolymer is prepared by polymerizing an olefin selected from the group consisting of alpha-olefins and vinyl aromatic monomers with at least one alpha, beta-unsaturated carboxylic acylating agent, and provided that when the olefin is vinyl toluene, then the alpha, beta-unsaturated carboxylic acylating agent is an alpha, beta-unsaturated dicarboxylic acylating agent. The compositions of the present invention are useful as drilling fluids as well as completion fluids. The esters of the carboxy-containing interpolymer or salts thereof provide beneficial viscosity, formation stabilization, emulsification and rheology properties to the fluids.
    • 本发明涉及包含盐水和液体烃的混合物的组合物,和(A)粘度增加量的至少一种含羧基的互聚物或其盐的酯,其中互聚物是通过将选自 由具有至少一种α,β-不饱和羧酸酰化剂的α-烯烃和乙烯基芳族单体组成的组,并且当烯烃为乙烯基甲苯时,α,β-不饱和羧酸酰化剂为α,β-不饱和羧酸酰化剂, 不饱和二羧酸酰化剂。 本发明的组合物可用作钻井液和完井液。 含羧基的互聚物或其盐的酯为流体提供有益的粘度,形成稳定性,乳化和流变性质。
