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 seepage parameters and describe the micro-seepage process. Firstly, the method and pore space descr iption of the pore network model are briefly introduced, and the characteristics and application range of quasi-static and dynamic pore network models are summarized.)
