摘　　要：本文以沁水盆地中5个煤层气富集区块为例,从遥感图像解译、地表岩层节理观测、井下煤层裂隙统计三个层次,对遥感线性要素、地表岩层节理、井下煤层裂隙的排列方向、组合方式进行了系统统计分析和研究,预测了煤层裂隙的优势方位和发育区,进一步选出了煤层渗透性相对较高的有利区块。This paper takes five CBM-rich blocks in Qinshui Basin as an example. Systematic statistics, analysis and research are made on key linear elements of remote sensing, joints in surface rock, orientations and compound mode of fractures in seams. The authors have made not only forecast of superior orientation and developed zones for fractures in seams, but also selection of favorable blocks with relatively higher seam permeability to a further step.
