The paper revealed the effctiveness and regularity of
polymer flooding by analyzing the dynamic production change in 4
years on 1-3 unit Es2 layer of shengyi section in shengtuo
Oilfield ,as well as made an analysis on the influencing factors
from dynamic and static behaviors of reservoir. It was assumed
that the static behaviors such as reservoir and sedimentary
characteristics had some influence on result , but the dynamic
behaviors such as injection2production flow curve ,abundance of
remaining reserves and injected polymer volume had more
important effect on the polymer flooding .
