| 摘 要： | 在分析聚合物驱与水驱驱替机理差异的基础上,对水驱预测的经验公式进行改进,建立了适用于聚合物驱的预测模型。预测模型可考虑聚合物溶液黏度、注入PV数及最大残余阻力系数等参数对聚合物驱效果的影响。预测模型预测大庆喇南和喇北东块的聚合物驱含水率曲线与实际含水动态吻合,预测提高采收率误差小于8%,结果可靠。预测模型所需参数简单、计算简便,可用于聚合物驱动态预测、效果评价及潜力分析。

| Abstract: | Based on analysis of the difference between polymer flooding and water flooding,an empirical formula for water flooding was modified and a new model for polymer flooding was developed.The main mechanisms of polymer flooding were considered in the new model,including the influence of polymer solution viscosity,injection pore volume,the maximum residual resistance factor,and so on.Predicted polymer flooding water-cut curves of two blocks in Daqing Oilfield were consistent with the real curves.The error of predicted enhanced oil recovery was less than 8%,so it was reliable.The model was simple and fast,and could be used for polymer flooding performance prediction,effect evaluation and potential prediction. |
