从渗流力学的基本规律出发，对几种不同类型储层驱替速度对提高油气采收率的影响进行了理论探讨。
On the basis of seepage flow mechanics, the impact of displacement rate on enhance oil recovery efficiency in different types of reservoir was investigated.
结果表明：单纯注入热水驱替效果不好，采收率提高幅度仅为0.20%；
The results indicate that the recovery ratio is only enhanced 0.20% simply by warm water driving.
近年来，提高原油采收率的重要措施是使用驱替液。
Recent years, the important measure to increase the crude oil recovery ratio is using displacing fluid.
