摘要:

        为了分析储水介质非均质性问题,采用了基于马尔柯夫地层序列分析的分布条件模拟方法,用转移概率矩阵的谱分析函数替代传统地质统计学中的变差函数,利用协同指示克里格方法和条件模拟建立结构模型。以华北平原为例,论述了模拟结构建立过程及其在水流模型中的应用。通过对模拟结果与实测数据的分析比较,认为模拟结果能够客观反映整个研究区的沉积规律,以岩性赋水文地质参数的方法更加客观准确地解决储水介质非均质性问题。分析了该方法的优、缺点,并提出了该方法深入研究的方向与思路。

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.

Key words: heterogeneity, Markov analysis, transition probability, co-inkriging, conditional simulation, hydro-geology parameter, North China plain
