摘要
为了刻画储水介质非均质性问题,本文采用了基于马尔柯夫地层序列分析的分布条件模拟方法,以转移概率矩阵的谱分析函数替代了传统地质统计学中的变差函数,利用协同指示克里格和条件模拟建立模型。文中对方法进行了简单表述,并将其应用于华北平原地区进行实例分析,模拟结果客观反映整个研究区的沉积规律。最后还分析了方法的优缺点,并提出了方法本身再深入研究的方向与思路。
The technique of the conditional simulation in porous media based on the analysis of Markovian stratum sequence is presented to solve the heterogeneity of porous medium. In the application of the technique, the variogram in traditional geostatistics is replaced by the spectrum analysis function of transition probability matrix, and the method of co-inkriging and conditional simulation is used to the modeling. The approach is applied to the example engineering in the North Plain of China, and the simulation results could objectively reflect the sediment rules in the plain. Finally, the advantages and disadvantages of the approach are analyzed, and its deep research aspects and ideas are pointed out.
