Study of evaluation technique for the effect of polymer floo

摘要: 介绍了一种新型水驱特征曲线方程,并以室内空白水驱实验和聚合物驱实验为基础,利用该方法对聚驱效果进行了测算,预测聚驱提高采收率为10.84%,该数值不但与室内实验结果10.20%十分接近,而且也在现场统计结果(10.03%~12%)的范围内,这为现场聚合物驱油效果评价提供了有益的参考。

Abstract: 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.
