According to the actual request of field production,using the equipment testing and theoretical analysis method,this paper analyzes the effect of the two stabilizers on viscosity,adsorption capacity,resistance coefficient,residual resistance factor and flooding effect of sewage polymer solution,and discusses its working mechanism.

Stability and displacement efficiency evaluation of high-concentration polymeric system;

This paper uses reservoir numerical simulation method to study the effect of injection rate on the displacement efficiency of polymer flooding and analyzes the reason of the effect.

Various practical application effects show that RMT logging technology plays an important role in many aspects such as saturation calcula- tion,water-flooded zone judgment,steam replacement effect evaluation and remaining oil saturation evaluation,etc.

Reservoir influence factors on polymer flooding efficiency;

In order to use sewage water from polymer flooding units in Daqing oil field, the relationship between polymer molecular structure and its flooding efficiency have been studied in this paper.
