“北一区断西聚合物驱油工业性矿场试验”是我国目前规模最大，周期最长的三次采油矿场试验项目。该文阐述了这个项目实施过程和取得的初步效果，分析了“大井距、多井组”条件下聚合物驱油的动态特点。试验结果表明：大面积工业性聚会物驱油的效果比先导性试验的效果好，油井含水率大幅度下降，原油产量成倍增长，为大庆油田大规模进行聚会物驱油展示了美好的前景。
“North Zone 1 Western polymer flooding industrial test” is China’s largest and longest period of the third oil field pilot project. This paper describes the project implementation process and the preliminary results obtained, and analyzes the dynamic characteristics of polymer flooding under the condition of “big well distance and multiple well groups”. The experimental results show that the effect of large-scale industrial agglomeration flooding is better than that of pilot test, the well water cut rate drops sharply and the crude oil output doubled, which shows a good prospect for large-scale agglomeration oil displacement in Daqing Oilfield .
