摘要
鱼骨井能够增大井筒与油藏接触面积,有效改善低渗透裂缝性油藏开发效果。但受井型结构及井网等因素的影响,在注水开发过程中出现诸多问题,如见水时间难以确定,含水上升速度较快等。用数值模拟技术,研究了采用直井注水、鱼骨井采油井网的低渗透裂缝性油藏的水驱开发效果。绘制了油藏中鱼骨井的水驱流线分布以及含水变化图版,总结出直井-鱼骨井混合注采井网开采的含水上升规律,对实际油藏开发具有一定的指导意义。
Fishbone well is of advantage for increasing the contact area of wellbore and reservoir and effectively improving development effect of low permeability fractured reservoirs.But affected by the well-type structure,the well pattern,etc.,its water drive characteristic is complex and presents many problems,for instance,the water breakthrough time is difficult to determine and the water cut rises quickly.Based on numerical simulation technique,this paper presents the water drive development effect of low permeability fractured reservoir with vertical injector plus fishbone producer well pattern,including drawing water flood streamline distribution and water cut changing chart,and summarizes the regularity of the water cut rising by using such a pattern,being of a certain significance to actual reservoir development.
