The pore size distribution is changed, with less large pores, basically with no micro pore, and with a large capillary force. The rock quartz content is high, the clay content is relatively low, as typical of the hard brittle shale. At the same time, the clay is dominated by illite, with a small amount of chlorite and illite/smectite mixed layer, not including montmorillonite, the expansion extent is small, the brittle shale parameters are between 0.49～0.77, the average value is 0.58. Test results provide some guidance for the shale mining method selection, the instability mechanism and the fracturing fluid design scheme in the shale gas development in the region., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=cHwF1a+ncGm0azvJd/0WEw==, pdfFileSize=3306380, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
