Abstract

Abstract:

In order to describe the heterogeneity of porous medium，this paper adopted the conditional simulation method based on Markov stratum sequence analysis, used eigensystem analysis of transition probability matrix instead of the traditional geo-statistics variogram, and constituted hydro-geological structure combined with co-inkriging method. In a case of North China plain, the paper discussed the process of modeling the conditional simulation of hydro-geological structure and the application to the GW numerical model. Through analysis and comparison, the simulation results reflect the sediment law in the whole study area. The method of evaluating hydro-geology parameter via lithologies observably solved the heterogeneity of porous medium in GW numerical model. The authors also analyzed the advantage and disadvantage of the conditional simulation and brought forward the direction and ways to the further study.
