摘要
煤的渗透性是控制煤层气在煤储层中流动的最关键参数。探讨煤的渗透率的相关影响因素及其变化规律,对于煤层气的勘探开采及动态开发效果具有重要的现实意义。本文详细地分析了裂隙系统、煤岩组分类型、煤的变质程度、有效应力、基质收缩、克林伯格效应等方面对煤储层渗透性的影响。
Permeability of coal is a most important parameter in controlling movement of CBM in coal reservoir. Studying of permeability of coal and relevant influencing factors and rules of their change is of important practical meaning in prospecting and mining and dynamic development of CBM. The paper investigates in de- tail the influence of many factors on permeability of coal reservoir, like cleavage and fracture system, type of macerals, degree of coal metamorphism, effective stress, shrinkage of matrix, Clinberg effect, etc.
