摘要： 考虑到油藏为多孔介质, 根据渗流力学原理, 建立水驱油多孔介质流固耦合换热控制方程, 对同一油
藏布置不同的井网进行数值模拟, 定性分析了采油过程中的压力、 剩余油分布规律, 以及不同体积分数区间内剩余
油的分布情况, 定量分析了剩余油的体积分数以及采油时间不同时的采收率。研究结果表明, 采油时间为5~9a
时, 剩余油的分布情况主要在死油区发生变化, 采收率变化平缓; 当同一油藏布置的井网不同时, 采油量也不同, 采
油量从大到小的顺序为5点法、 9点法、 排状法; 当注水强度保持不变时, 从采收率的角度看, 5点法井网最优。

Abstract: Water-driven oil in porous media fluid and solid coupled heat transfer control equations was established by the theory of percolation mechanics and the sandstone reservoir was porous medium. Different well pattern was established for the same reservoir numerical simulation, qualitative analysis of the process of oil pressure, the remaining oil distribution, and the various concentration range the proportion of oil, quantitative analysis of the volume fraction of the sum of the remaining oil and various oil recovery year. The results show that 5 to 9 years of oil remaining oil distribution changed in the inert area, during this time recovery changed smoothly; Analysis of a variety of oil recovery wells arrangement size was that five-spot well pattern was larger than nine-pot well pattern, and nine-spot well pattern was larger than Line shape well pattern. When the water intensity constant, from the perspective of recovery. For this reservoir five-spot well pattern was the best well pattern.

Key words: Oil reservoir, Well pattern, Recovery efficiency, Porous medium, Transfusion
