| 摘 要： | 制取了非离子氟碳表面活性剂FPEG400和FPEG600，并与甲醇进行复配得到了复配表面活性剂。室内水锁实验研究结果表明：水驱过程中加入该复配表面活性剂后。岩心的渗透率损害程度得到较大的降低。油相渗透率上升，提高了采收率。

| Abstract: | In this paper,non-ionic fluorocarbon surfactants FPEG400 and FPEG600 were prepared,then ac- ted with methanol as composite systems, in which, they exhibited excellent synergism. The indoors experiment results showed that,during the process of water flooding,when adding the composite surfactants to water, the damage to penetration rate of the core greatly reduced,and the relatively oil permeability increased,hence the recovery improved. |
