摘　　要：大庆油田萨北开发区,在葡一组一类油层聚合物驱取得显著效果后,二类油层注聚技术逐步开始工业化推广。本文根据北二西西块实际注聚经验,针对二类油层及葡一组一类油层的差异,总结了二类油层聚驱开发中压力、产液能力、含水下降幅度、增油倍数、油层动用程度等开发指标的变化规律;针对二类油层聚驱过程中不同阶段及油层特点,提出注聚前调剖,见效期阶段规模分注、个性化调整,低值期阶段以压裂增产提液,含水回升期阶段聚中调剖、层段细分重组为主的二类油层聚驱配套调整技术、注聚中个性化的调整技术;并从油层整体及不同沉积单元两个层面上,对二类油层聚驱开发效果进行评价,对指导其他二类油层区块的聚驱开发具有重要的意义。The technology of polymer flooding started to be put in industrialized practice in the Class Ⅱ reservoir of Sabei area in Daqing oilfield after the significant effect had been achieved in the Class Ⅰ reservoir.According to the experience of polymer flooding in the west area of Beierxi and the deference between the Class Ⅰ and Class Ⅱ,the regularities of the pressure,the liquid production rate,the range of water-cut dropping,the multiples of increasing oil and the oil producing degree of reservoir were summarized in this article.It was propounded that some special Class Ⅱ reservoir polymer flooding adjusting methods which included profile control before injecting polymer,spreading separate flooding in effective stage,fracturing in low water-cut stage,profile control in water-cut raising stage through contrasting the differences between the Class Ⅰ and Class Ⅱ reservoirs.It was estimated that the polymer flooding effect in Class Ⅱ from the whole reservoir and the two different sedimentary units.It was significant to direct the polymer flooding development.
