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 ,聚合物驱取得了明显效果 Gudao Oilfield West injection zone in March 1997 after the injection of agglomeration, high permeability layer effectively blocked, water absorption profile has been significantly improved. During the injection-co-polymerization period, polymer flooding has been expanded by implementing measures such as precipitation or stoppage of water wells in the periphery of the injection zone, amplification of production pressure in the oil well, and adjustment of the injection velocity of the injection polymer injection well. The polymer flooding has achieved remarkable results
