摘要
“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。
The industrial field test of polymer flooding in Duanxi of block Beiyi, Daqing oil field is currently a tertiary enhanced oil recovery project with the largest scale and longest period in China. This paper describes the implementation procedure of the project and the initial results obtained, it also analyzes the production performances of polymer flooding with wide well spacing and multiple well groups. The test results show that the effects of large scale industrial polymer flooding are superior to those of pilot tests. The dramatically decreased water cut and doubled oil production rate show bright prospects for large scale polymer flooding in Daqing oil field.
