| 摘 要： | 聚合物驱提高采收率的能力在10％左右，聚合物驱后油藏仍有约50％的原油未采出。聚合物驱转水驱后，含水率上升，产油量递减加剧。笔者通过对国内外油田聚合物驱后进一步提高采收率的现场试验与室内实验结果的调研、分析和评价，筛选出聚合物驱后进一步提高采收率的技术。

| Abstract: | Oil recovery is enhanced about 10%by polymer flooding,and there is still almost 50%crude oil remained underground after polymer flooding.The water-cut increases quickly and the oil output decreases greatly in the water flooding after polymer flooding.According to the investigation,analysis and evaluation of the results from field tests and laboratory experiments to further enhance oil recovery at home and abroad, several technologies to enhance oil recovery after polymer flooding were selected. |

| Keywords: | after polymer flooding remaining oil distribution enhanced oil recovery replacing technology |
