将电镜扫描图片分块化后统计各分块孔隙密度，获得扫描区域内孔隙率分布矩阵，将矩阵进行三维样条曲面插值，绘制相应的等高线，并保存为图片。(After the electron microscope scanning image is divided into blocks, the pore density of each block is calculated, and the porosity distribution matrix in the scanning area is obtaine

孔隙网络模型广泛应用于多孔介质的微观模拟中,已经可以较好地实现对渗流参数的定量预 测,并用来描述微观渗流过程。首先对孔隙网络模型建立方法和孔隙空间描述作了扼要介绍,总结了 准静态和动态两类孔隙网络模型的特征及应用范围,(The pore network model is widely used in the microscopic simulation of porous media, and it can be used to quantitatively predict the seepag

实验可以用，主要应用于数字岩心的建立，基于马尔科夫链法，建立孔隙网络模型(Experiment can be used, mainly used in the establishment of the digital core, based on the markov chain method, the pore network model is established)
