根据海上油田开发特点和典型聚合物驱油藏的开发实践，建立包括驱替效率、降水效果和增油效果评价指标等三方面的聚合物驱效果评价指标集；考虑油田在聚合物驱投入、产出过程中经济因素的影响，研究了经济极限吨聚增油量与原油价格的关系，提出以吨聚增油量为基础的效果分级评价方法，并建立相应的各个效果评价指标的四级评价标准。实际油田应用表明，建立的方法可以比较全面地评价海上油田聚合物驱的效果，定性半定量地确定聚合物驱的开发水平，对海上油田聚合物驱的开发具有一定的指导作用。

According to development characteristic and development practice of typical polymer flooding reservoir in offshore oilfields, the polymer flooding evaluation index sets including evaluation index of displacement efficiency, precipi- tation efficiency and incremental oil effect were constructed. Considering influence of economic factors in investment and output process in polymer flooding, classification evaluation of development effect based on incremental oil per ton of poly- mer was proposed by investigating the relationship between economic limit of incremental oil per ton of polymer and crude oil price. And four evaluation criterions of the corresponding evaluation index of development effect were established. Oil- field application shows that the established method can run a comparatively comprehensive evaluation of polymer flooding in offshore oilfield and determine the development level of polymer flooding qualitatively - semi quantitatively. Thereby it can provide a certain guiding role for polymer flooding in offshore oilfields.
