Study of evaluation technique for the effect of polymer floo

A new water drive characteristic curve equation is introduced in this paper. Based on the lab experiment of water flooding and polymer flooding, this new method is used to forecast the effect ofpolymer flooding, and the oil recovery is enhanced by 10.84% which is very close to the lab experiment result which is 10.20% and also in the range of field statistics( 10.03%~12% ). It's an useful reference for the effect evaluation of polymer flooding.
