运用更新改造项目评价的“有无对比”法，以双河油田Ⅱ5层高温聚合物驱和优化水驱数模结果为对比基础，探讨了聚合物驱经济评价方法和评价指标，并进行了现金流量分析和盈亏平衡界限计算。评价结果表明，双河油田Ⅱ5层高温聚合物驱试验经济效益较高，其评价方法及评价指标可行。 Based on the comparison of “no comparison” method of evaluation of renovation projects with the comparison of the results of high temperature polymer flooding in Ⅱ 5 layers of Shuanghe Oilfield and the numerical simulation of waterflooding, the economic evaluation method and evaluation index of polymer flooding were discussed, and the cash Traffic Analysis and Breakeven Bound Calculation. The evaluation results show that the high-temperature polymer flooding test of Ⅱ 5 layer in Shuanghe Oilfield has high economic benefits, and its evaluation method and evaluation index are feasible.
