摘要
本文简要介绍了聚合物驱防窜机理和在大港油田港西四区进行的聚合物驱防窜先导性试验的实施简况,并着重对其效果进行了分析。试验结果表明,经聚合物驱防窜处理的井聚合物突破时间得到有效推迟,产油量明显增加,含水显著下降,可使聚合物驱的采出程度进一步提高。
The paper presents the fingering-resisting mechanism, and fingering-resisting pilot test with polymer flooding for No. 4 area, Gangxi oilfield. The result of the field pilot test shows that the polymer breakthrough time has been effectively delayed in producers with polymer fingering-resisting process, meanwhile the oil production has been increased observably and water cut decreased, as well. The sweep efficiency of polymer flooding can be improved. SOme factors of affecting the fingering resisting effectiveness with polymer flooding are also given in the paper.
