摘　　要：针对复杂断块油藏注水开发后期高含水高采出程度的特点,大港油田在A区开展了污水聚合物驱工业化现场试验。现场取得了较好的增油效果,通过对相关指标分析,明确了A区聚合物驱油的影响因素,并在此基础上提出了进一步提高采收率的方案部署,预计提高采收率12%以上。根据室内物理模拟实验证实聚/表二元驱可提高采收率值大于20%,聚/表二元驱油藏数值模拟预测,提高采收率可在聚合物驱的基础上再提高4.76个百分点,使油田最终采收率达到50%以上。In the late stage of water flooding development,the characteristics of complex fault-block oil reservoir is in high level of water cut and recovery.Dagang Oilfield in Gang Xi Third District has carried out industrial field tests of sewage polymer flooding.The better enhanced oil recovery has been achieved. Through analysis of relevant indicators,the influencing factor of polymer flooding was defined.And the forward proposals to further enhance oil recovery was designed.Enhanced oil recovery is expected to more than 12%.
