It is also obtained that with the water-oil viscosity ratio increased, the enhanced oil recovery rate is increasing. Meanwhile,the rate of increase slowed down when the viscosity ratio is more than 8.4.
提出不同水油粘度比对驱油效率的影响,得出随着水油粘度比增大,提高采收率幅度不断增加,但在粘度比大于8.4后,增加幅度变缓。

The development effectiveness of water flooding for the heavy oil reservoir with edge water is poor because of the high oil viscosity, high mobility ratio and the invasion of edge water.
注水开发多年的具边水的普通稠油油藏的原油粘度高、流度比大，加之油藏非均质及边水入侵的影响，其注水开发效果较差。
Moreover, the viscosity of water didn't increase due to the addition of MD-1, and no changes of its oil-water current ratio was observed.
MD 1膜驱剂的加入不增加驱替流体的粘度，不改变油水流度比，膜驱油机理与聚合物驱不同。
For the high oil-water viscosity ratio of common heavy oil reservoir, the development effect becomes worse and worse with the reservoir coming into the high water production phase.
普通稠油注水开发油藏由于油水黏度比大，面临进入高含水中后期水驱开采效果越来越差的普遍矛盾。
