摘　　要：通过双河油田二类储量油藏聚合物驱研究及应用,总结出以提高井网控制程度和改变液流方向宗旨,优化聚驱井网,注入聚合物前采用整体调剖封堵大孔道,合理选择适应于二类油藏的驱剂,针对不同的非均质储层采用不同聚合物浓度以及适时提出配套工艺措施等技术对策,形成了一套提高二类储量高温聚合物驱效果的作法,对二类储量聚合物驱推广应用有借鉴意义。目前双河油田Ⅲ油组、北块Ⅳ1-3、江河区V上已开展了高温聚合物驱工业化推广应用阶段,取得了明显的降水增油效果。Through research and application of class Ⅱ reserves with polymer flooding in Shuanghe oilfield,according to the purpose to enhance well-pattern controlling degree and change the flow direction,optimize the well-pattern of polymer flooding,block larger reservoir channels by adjusting profile overall before injecting polymer,choose reasonably flooding agent which adapted to this Ⅱ-class reservoir,adopt polymer with different concentration according to different non-homogeneous reservoir,and put forward timely matching technical countermeasures,therefore formed a set of measures to improve the development effect of class Ⅱ reserves with high temperature polymer flooding,which provides a referential evidence for development of class Ⅱ reserves with high temperature polymer flooding. At present,Ⅲ oil group and Ⅳ1-3 oil group of north block in Shuanghe oilfield,the top section of Ⅴ oil group in Jianghe areas have been in the stage of industrial application of high-temperature polymer flooding,and obvious effect of increasing oil and decreasing water production has been achieved.
