Natural Fracture Net and Mineral Contents 2.1 Observation of macro-scale nature fracture The main pay zones of Qinshui Basin coal bed methane are named as 3# and 15# coal seams. Through downhole observations, SEM and X-ray diffraction analysis, we can see fillings in coal fractures as that most of the clay minerals are kaolinite or illite, and the carbonate fillings in both macro- scale fracture and miro-scale fracture are also abundant.	cache/esrj-61633.pdf	txt/esrj-61633.txt
