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。
The heavy oil from TK427 well and S48 well in Tahe field is selected as the sample. The viscosity is tested in conditions of various water ratio and GLR, which have a main effect on the viscosity.
测量了塔河油田的TK427、S48井在不同压力温 度下的原油粘 度，并对影响稠油粘 度的主要影响因素——含水率和气油比进行了 敏感性实验。
Research shows that with the increased CO2 injection, dissolved gas oil ratio, volume expansion coefficient and coefficient increases, viscosity decreases, bound water volume expansion.
研究表明：随着CO2注入量增加，溶解油气比、体积系数和膨胀系数增大，粘度降低，束缚水体积膨胀。
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。
