| 摘 要： | 应用非线性盈亏平衡分析方法可求出注水开发油田年最低经济极限产量,而Hubbert模型和Lp～Lp/Np关系可导出时间与产油量、产液量及含水率等开发指标之间的关系,将三者结合可得到最大经济极限产量下所对应的经济极限含水率、经济极限可采储量等经济开发指标。应用模型预测累积产油量的相对误差0.09%～3.77%,精度高,符合生产实际。该方法操作简便,利于广泛推广应用,可为开发及生产决策提供依据。

| Abstract: | Nonlinear breakeven analysis can be used to derivethe lower economic limit rate of waterflooding oilfields,while Hubbert model and LpLp/Np correlation to determine the relationship between time and oil output and that between fluid production and water cut.The combination of these three methods can be used to achieve economic recovery indexes such as economic limit water cut and recoverable reserves at upper economic limit rate.The relative error of predicted cumulative oil recovery is3.77%. |

| Keywords: | breakeven analysis prediction economic limit rate economic development index |
