应用马尔柯夫过程的原理和方法，建立起描述煤层形成过程或显微序列的数学模式，进而通过对研究实例中煤层结构以及煤岩分层孔比表面积的模式拟合，可以模拟出各种显微煤岩类型在煤层中的分布部位以及煤层中煤层甲烷的有利储存部位，对厚煤层物性和储气性能的非均质性特征作出预测，为煤层气开采地质条件评价提供了一条新的思路。 Based on the principle and method of Markov process, a mathematical model describing the formation process or microscopic sequence of coal seam is established, and by means of the model fitting of the coal layer structure and the hole specific surface area of ​​coal rock in the research example, The distribution of micro coal and rock types in the coal seam and the favorable storage of methane in the coal seam predict the heterogeneity of the physical property and gas storage performance of the thick coal seam and provide a new method for evaluating the geological conditions of coalbed methane mining Ideas.
