孔隙网络模型广泛地用于同多孔介质有关的微观模拟中.本文简介了利用网络模型研究储层渗流规律的基本思想、主要步骤以及网络模型同其它微观模型相比较的优缺点,总结了在微观渗流研究中使用的两大类网络模型(准静态网络模型和动态网络模型)的特征及其适用范围,综述了目前网络模型在研究渗流中的应用现状以及国内外研究比较活跃的几个方面,最后分析了网络模型今后的发展趋向.
The pore network model is widely used in the micro-simulation of porous media.In this paper, the basic idea and main steps of using the network model to study the percolation law of the reservoir are introduced. The advantages and disadvantages of the network model compared with other micro-models are summarized. The characteristics of two kinds of network models (quasi-static network model and dynamic network model) used in percolation research and their applicable scope are summarized. The current application of network model in the study of seepage flow is reviewed, and several aspects of active research at home and abroad are summarized. Finally, the future development trend of network model is analyzed.
