摘　　要：用方程系数法研究了以OP—10为非离子表面活性剂、正构烷烃为油相、正丁醇为基醇、正己醇为追加醇的体系形成中相微乳液的规律,确定了该体系的最佳含盐量方程。非离子表面活性剂体系具有特殊的性质,其最佳含盐量对油溶性和水溶性基醇的方程都能满足。In this paper, the formulation of middle-phase microemulsion systems with a aonionic surfactant selected, OP-10, for EOR is researched by using the equation coefficient approach. The composition of the systems studied is: OP-10, a basic(n-butanol) and aa additional(n-hexanol) alcohols, and sodium chloride constitute the aqueous phase; normal alkanes C6-C12 serve as the oil phase. Following equations for the optimum salinity of the aqueous phase, S~*, in g/100ml are established, lnS~* = 0.0536(ACN) +0.1444A-0.0376t-1n1.07C_(op) + 3.2703 S~*= -[0.1058(ACN) +0.223] A+ 0.4148(ACN) - e^(0.0.78)- 1.07C_(op) + 9.674 in which ACN denotes the alkane carbon number;A-the hexanol concentration,％, t-the temperature, ℃; Cop-the OP-10 concentration, %.
