Abstract: The appropriate HLB of emulsifier was screened and evaluated, and emulsion with strong stability was selected. Static test results showed that emulsion had good resistance and salt resistance. With the increasing salinity, stable performance of the emulsion decreased slightly. The flow resistance can be improved 140 times when the liquid viscosity was high, illustrating that the emulsion system had the good displacement effect in high temperature and salinity conditions. Displacement experiments show that the matching of emulsion drops with pore throat decides transport of emulsion liquid in porous media capabilities. 

摘要: 对合适 HL B值的乳化剂进行了筛选和评价, 优选了具有较强稳定性能的乳状液。静态测试结果显 示乳状液具有较好的耐温和耐盐性能, 随着矿化度的提高, 其稳定性能略有降低, 但是幅度不大。该乳状液体系具 有很高的黏度, 渗流阻力能够提高1 4 0倍左右, 说明乳状液体系能够在高温高盐条件下取得很好的驱替效果。驱替 实验还表明乳状液滴与孔喉的匹配性决定了乳状液在多孔介质中的运移能力。
