摘　　要：随着水平井技术的发展与成熟,以单水平井为主的开发模式已转化为以水平井井组整体开发为主。利用数值模拟方法研究了水平井与直井五点法井网微单元的流线特征与水平井流入量分布特征对开发效果的影响,探讨了智能井技术在水平井井网中的应用。结果表明,五点法井网微单元的流线特征决定了水平井流入量的分布特征,流入量分布越不均衡,注水开发效果越差,而通过采用智能井技术可以实时调控水平井的流入量分布,从而有效减缓注入水的突进速度,增加波及系数,提高油田的开发效益。With the development of horizontal well technology, the exploiting pattern has been gradually changed from single horizontal well to horizontal well pattern. The streamline characteristics of horizontal and vertical five spot well pattern, the impacts of inflow performance on development results were investigated using numerical simulation. The application of smart well technology was also discussed. The results indicate that the streamline distribution determines the horizontal well＇s inflow performance. The more unbalanced inflow distribution the worse the development results. The smart well technology can adjust the horizontal well＇s inflow distribution to control the water cut effectively, to increase the sweep efficiency and to improve the oil field development.
