| 摘 要： | 宽分子量分布的石油磺酸盐在低浓度时有正丁醇、正构烷烃、盐存在的情况下能成中相微乳液。研究了盐浓度、烷烃种类、醇浓度对该体系中相微乳液的形成及特性影响，得到中相微乳液的特性参数；最佳含盐量Ｓ＾＊、增溶参数σ、盐宽△Ｓ、界面张力γ等，并从理论上进行了探讨。采用模拟驱油装置测定了体系的驱油效率，对优化驱油体系设计具有重要意义。

| Abstract: | At low concentration (0.4%), in the present of n-butanol, alkanes and brine, petroleum sulfonate (SPS) which has wide range of molecular weight, can form middle phase microemul sion. Using salinity, n-butanol scanning and interfacial tension, we investigated the influence of salinity, n-butanol and kind of alkane on the formation and characteristics of the middle Phase microemulsion of 0.4% SPS/ n-butanol/NaCl/alkane system at V_oil/ V_water=1: 4. Using mimic oil recovery, we investigated the influence of salinity on oil recovery efficiency. It showed in this study that the maximum oil recovery efficiency was connected with optimal salinity and optimal interfacial tension. The results are of particular importance to design slug formation. |
