摘　　要：建立多孔介质微观模型是进行微观渗流研究的基础。列举几种常见的多孔介质微观模型,概述其应用和重要性。调研多孔介质重构方法:物理实验方法、数值重构方法和用于理论研究的随机方法,分析每种方法的基本思想,并在此基础上总结了每种方法的优缺点及其适用性。对比发现,数值重构方法成本低、需要信息量少,可以广泛应用。而在诸多数值重构方法中,马尔科夫链-蒙特卡洛方法(MCMC方法)具有计算速度快、重构效果好和适用范围广泛的特点。通过多孔介质重构实例验证了MCMC方法的优点。最后展望了重构方法的发展和应用。Building micro model of porous medium is the basis of studying micro permeation.In this paper,several common porous medium micro models were listed and their application and importance were summarized.Then the reconstruction methods of po rous medium micro models,including physical test,numerical reconstruction method and theoretical stochastic method,were stud ied.The basic thoughts of these methods were analyzed,and further more,each method’s characteristics and applicability were summarized.Through the comparison,the numerical reconstruction protruded with the advantage of low cost and requirement for less information,and could be applied widely.Among the numerical reconstruction methods,Markov chain-Monte Carlo（MCMC）,characterized with high-speed calculation and good reconstruction effects,was better for wider application.The above advantages of MCMC was proved in porous medium reconstruction cases.At last,the paper foresaw the paper of the development and applica tion of MCMC method.
