Research on the reconstruction method of the micro-model of porous medium

Wang Bo and Ning Zhengfu(College of Petroleum Engineering,China University of Petroleum(Beijing),Beijing 102249,China)  
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.
