双河油田Ⅱ5层高温聚合物驱试验经济效果评价

Economic Effects Evaluation of a High Temperature Polymerflooding Pilot in Shuanghe Oilfield

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。

By using the numerical simulation results of hightemperature polymerflooding and optimized waterfloodingin Zone Ⅱ5 in Shuanghe oilfield as the basis ofcomparation, we studied the evaluation procedures andindexes of polymerflooding with the comparative analysismethod of technical innovation project evaluation,analyzd cash flow and calculated profit and loss balancelimits .Evaluation results show that the economic benefit ofthis polit test is high and the evaluation procedure andindexes are practical.
