摘要
Results of the global shale gas resources show that minable resources of global shale gas are 187 trillion cubic meters （tern）, of which China accounts for 36 tcm （about 20% of the total amount）, which is mainly distributed in the Sichuan Basin, Yangtze Terrace, and Ordos Basin. From 2009 to 2012, China completed an accumulative number of 129 drilling wells related to shale gas, including 46 investigated vertical wells, 55 exploration wells and 28 evaluation wells, with 2012 production ranging from 25 million cubic meters （mcm） to 30 mcm.
