摘　　要：胜一区注聚试验明显见效后 ,随着油井含水的下降 ,见聚浓度的增加 ,有杆泵油井泵效下降 ,回压升高 ;电泵井产液量下降 ,吨液耗电量增加。根据聚合物驱油的矿场资料 ,分析了聚合物驱对举升工艺的影响 ,并针对存在的问题采取了确定合理沉没度、加药降低油井回压、电泵改抽油机、大泵改小泵和螺杆泵等措施 。After being the mended stage of polymer flooding in block 1,New problems of the lifting technology was put forward. This paper analyzed the influence of lifting technology by polymer flooding according to the polymer flooding pilot test data. In the light of the problem, appropriate measures have been taken, which showed obviously economical effect.
