摘要
孤岛油田西区注聚区 1997年 3月投入注聚后 ,高渗层得到有效封堵 ,吸水剖面得到明显改善。注聚期间 ,通过实施注聚区外围水井降水或停注、油井放大生产压差和调整注聚井注入速度等开发措施 ,扩大了聚合物波及体积 。
After polymer flooding in Mar. 1997 in Western Region of Gudao Oilfield, the high permeable formation is plugged up effectively and the injectivity profile is improved. During the flooding through stopping or decreasing water flooding to the peripheral water wells, amplifying producing differential of oil wells and regulating injection rate of polymer flooding, the swept volume of polymer is expanded and the development effectiveness of polymer flooding is obviously achieved.
