| 摘 要： | 建立地层孔隙网络模型描述微观孔喉特征,利用逾渗方法计算基于微观渗流机理的相对渗透率曲线,并将之应用到数值模拟计算中,给出考虑微观渗流特征的方程,并进行数值求解,得到地层中流体分布特征。实例分析表明该方法可以得到基于微观特征的剩余油分布数量和形式,为调剖堵水、化学驱提供技术参数,实现微观渗流机理与宏观计算的结合。

| Abstract: | The microscopic pore structure and driving mechanism have a great influence on the distribution of the remaining oil during the high water-cut development stage of an oilfield.The influence of the pore-throat structure on oil recovery is not considered in the conventional reservoir simulation method.The network model of reservoir pores is built to describe the characteristics of microscopic pore structure.The relative permeability data based on microscopic flow mechanism is calculated using percolation theory,and is used in reservoir simulation.The Equations are built and solved numerically to give the distribution of fluids in the cores,which consider microscopic flowing mechanism.This method combines the microscopic flowing mechanism with macroscopic calculation.Practice shows that the amount and distribution form of the remaining oil can be obtained using this method,which provides basic technical parameters for profile control work and chemical flooding processes. |
