| 摘 要： | 通过对煤心样品的观察研究得出,煤心具有不同的形状,此形状受煤体结构制约,区分不同煤心形状,能确定煤层中不同的煤体结构。利用该煤体结构能估算出煤储层渗透率的大小,这对煤层气选区评价,煤层射孔压裂层段的选择,煤与瓦斯突出带的确定,提供了可靠的科学依据。

| Abstract: | Based on observation of coal cores it is concluded that the coal core consists of different forms in shape,controlled by coal block texture.Identification of coal core forms may determine coal block texture.The permeability of coal seam may be speculated using coal block texture.It would provide reliable scientific fundamental data for determining perforated interval,potential gas outburst belt. |

| Keywords: | coal block texture coal core forms permeability |
