| 摘 要： | 根据岩石润湿性的衡量标准,用光学投影法测定岩石接触角,对生物酶改变岩石表面润湿性进行了实验研究,包括生物酶与岩石作用后岩石润湿性的变化、毛管力的变化以及粘附功的变化。实验结果表明,生物酶与岩石作用后,可以明显改变水驱油毛营力的大小,可以加速剩余油的流动,从而提高油藏的采收率。

| Abstract: | Based on the measuring standard of rock wettability and using optical projection to measure contact angle of rocks, the experiments on the changing wettability of rock surface by biological enzyme include the changes of rock wettability, capillary force and adhesion work after the act of rock with biological enzyme. Research results show that the biological enzyme can change capillary force of water -flooding oil evidently, accelerate flow of remaining oil, and enhance the recovery efficiency of oil reservoir. |
