煤储层渗透率的非均质性模型

Model of the Hetergeneous Permeability of Coal Reservoir

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渗透性的模式拟合，对厚煤层渗透率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 upon the principle and method of Markov chain, the mathematical model used to describe the forming process of coal seam or microsequence is established. The heterogeneous characteristics of permeability of coal reservoir is predicted; and the model of coal seam structure and permeability is fitted; a new way of evaluating the mining geological conditions of CBM is put forward.
