中文说明： 本文主要结合格子Boltzmann方法和随机网络法来模拟孔隙尺度下单相气体的二维流动。分别在重构的和真实的孔隙结构图像上进行渗流数值实验，计算传导征参数－渗透率。一些计算结果不仅验证了经典的渗流理论，还在实际算例中探索新的渗流规律。为我们后期页岩气藏渗流机理研提供支持。
English Description：
In this paper, lattice Boltzmann method and stochastic network method are combined to simulate the two-dimensional flow of single-phase gas in pore scale. Numerical experiments were carried out on reconstructed and real pore structure images to calculate the conductivity parameter permeability. Some calculation results not only verify the classical seepage theory, but also explore new seepage laws in practical examples. It provides support for the research of shale gas reservoir seepage mechanism in the later stage.
