Abstract
To get a set of suitable petrological research methods for terrestrial shale gas reservoir, quicken the pace of shale gas research and solve the dispariy btweenesting technique,ppraisal method ad reference standard, this paper analyzed the petrology of shale gas in the sections Chang 7 and Chang 9 in the Xiashiwan area, southeast of the Erdos basin using field drill core description, thin section analysis, SEM analysis and X-ray diffraction against the standard DB61/577-2013The Analysis and Test Methods of the Sample in Shale Gas Well. The testing results indicated that the shale gas reservoir is complex in lithology, high in content of clay minerals, low in brittle minerals of quartz and carbonate, which are hard to be studied in detail by routine testing method. So, the tested samples are pretreated and more equipment used, forming a research system for terrestrial rocks as follows: drill core description, thin section identification, SEM and energy spectrum, and X-ray diffraction.关键词
