| 摘 要： | 针对在油气储层随机模拟中马尔可夫链模型的不同方向的转移概率矩阵求取困难的问题，提出一种二维剖面中不同方向的转移概率矩阵求取方法，这种方法的提出使得不同阶次的各向同性和各向异性的邻域系统的转移概率矩阵的求取变得容易可行。随后，对不同邻域系统的马尔可夫链模型采用蒙特卡罗抽样方法进行了储层岩相随机模拟试验。最后比较了不同邻域系统岩相模拟的结果并探讨了在储层研究中的适用性。

| Abstract: | For the difficulty of getting transition probability matrixes in various directions in Markov chain(models),the paper presents a method to figure out it,which makes getting transition probability matrixes of (different) neighborhood systems of Markov chain models easier and more feasible.Furthermore,Monte Carlo sampling method is used to simulate reservoir lithofacies,based on different neighborhood systems of Markov chain models.In the end,the different simulated results are compared and the characteristics and applications of different neighborhood systems in the study of reservoir are discussed. |

| Keywords: | Markov chain neighborhood system transition probability matrix stochastic simulation of lithofacies |
