摘　　要：针对聚合物驱油过程中机采井生产状况进行了深入的分析和研究，总结出了机采井在聚合物驱油过程中，随着采出液聚合物浓度的增加，导致油层压力升高，井底流压降低的现象，并使采出井流压与产液关系发生变化，IPR曲线发生变化，产液指数下降，抽油机电流变大，扭矩利用率变大，悬点最大载荷变大等规律。针对上述影响规律，在今后聚合物驱油工业推广中，在合理预产，合理放大生产压差，合理优选机采井生产参数，降低采液指数等方面具有重要意义。The authors summarizes that on the mechanical recovery well in the course of polymer drive, as the density of produced liquid polymer increases, then the oil reservoir pressure increases, the flow pressure at well bottom decreases,and the relationship between the flow pressure of produced well with liquid producing changes, IPR curve changes,liquid producing index decreases etc. The above rules have signifiant meaning in leasonably predetermining output,reasonably enlarging the production pressure difference, reasonably optimum selecting the production parameters ofmechanical recovery well and decreasing liquid producing index etc.
