| 摘 要： | 三次采油技术中研究和应用较多的是包含表面活性剂的各种化学驱油技术，包括三元复合驱、二元复合驱以及表面活性剂驱等。表面活性剂在这些驱油技术中起着重要作用．它主要是通过降低油水界面张力和提高毛细管数达到提高采收率的目的。对于普通油藏，表面活性剂驱油剂的研究比较成功，应用效果也比较理想，如石油磺酸盐、烷基苯磺酸盐可与地层流体配伍，形成超低界面张力，达到提高采收率的目的。

| Abstract: | In view of the characteristics of high temperature and high salinity of reservoir, oil displaceable surfactant ROS featuring thermal stability and salt endurance was developed. Field tests in two fault blocks were carried out by injecting ROS surfactant after profile control in Huabei Oilfield. The field test results showed that ROS surfactant had good thermal stability and salt endurance, and significant effect in oil increment could be seen by injection of oil displaceable ROS surfactant on the basis of p... |
