本文应用迂渗(percolation)理论,根据油藏裂缝特征参数,给出了油井周围裂缝系统延伸范围的分析计算和计算机模拟方法,从而解决了裂缝性油气藏自喷开采后剩余油分布区域的数学描述问题,为打加密井提高采收率确定布井方案提供了依据。文章列出了两个实例,计算和模拟结果与开发实际相一致。
In this paper, percolation theory is used to analyze and calculate the extension range of the fracture system around the oil well according to the characteristic parameters of reservoir fractures so as to solve the problem that the mathematical model of residual oil distribution area Describe the problem and provide a basis for determining well drilling plan to increase the oil recovery rate. Article lists two examples, calculation and simulation results consistent with the actual development.
