【摘要】 采用鱼骨井技术采油能够有效增加生产井与油层接触面积,改善油藏开发效果,但受鱼骨井井型参数及注采井网等因素的影响,油井见水时间、含水变化与含水上升速度等开发指标难以预测。基于油藏数值模拟技术,研究了采用直井注水鱼骨井采油的注采井网模式对水驱开发动态指标的影响,描述了采用该种注采井网组合的水驱流线分布、压力场分布以及含水上升规律,对油田开发具有一定的指导意义。更多还原

【Abstract】 Fishbone well can increase contact area with reservoir and improve development effect.However,it is difficult to forecast development indices such as water breakthrough time,water cut changes and water cut increase rate as affected by parameters of fishbone well structure and flooding pattern.Based on numerical simulation,this paper studies the impact of the flooding pattern of vertical injector and fishbone producer on production performance,and introduces the flooding streamline distribution,pressure field distribution and water cut increasing trend of this flooding pattern.The study has an instructive significance to oilfield development.更多还原
