表面活性剂驱油是三次采油的主要方法之一。本实验采用真实砂岩微观模型驱替实验技术，结合长２、长６油层来探讨表面活性剂的驱油机理及其对驱油效率的影响。实验表明，利用该项技术进行活性水驱油实验来研究其对驱油效率的影响是可行的。
Surfactant flooding is one of the main methods of tertiary recovery. In this experiment, real sandstone microscopic model displacement experiment technique was used to investigate the mechanism of surfactant flooding and its effect on flooding efficiency by combining Chang 2 and Chang 6 reservoirs. Experiments show that the use of this technology for active water flooding experiments to study its effect on flooding efficiency is feasible.
