| 摘 要： | 从煤岩学的角度，对煤储层裂隙的研究方法进行辩析，提出有关裂隙的定义。分析认为，主裂隙的展布方向是渗透性的优势方位；裂隙几何形态参数是渗透率大小的量级；连通性裂隙网络是高渗透区的良好标志，为预测煤储层渗透性能提供一种简单易行的研究方法。

| Abstract: | The study methods for coal reservoir fissures are analyzed from the view I)oint of coal petrology,and the deft nitions related to the fissures are presented. It is considered that the distribution direction of main fissure is the optimal direction of Permeability; the parameter of fissure geometry is the magnitude of l)ermeability;an'l the connected fissure network is the better indication of high I)ermeable area. Therefore, a siml)lificd method is Presented for the prediction of coal reservoir permeability . |
