摘要
1 Introduction With almost five years of efforts, we have made major breakthrough and important advances in shale gas in many areas, such as the marine and continental shale in Sichuan Basin, the continental shale in Erdos Basin and the transitional shale in North China. China has begun shale gas productivity constructions in many shale gas development demonstration areas, such as Chongqing Fuling and Sichuan Changlin-Weiyuan, where early stage large-scale development of shale gas has been started （Zhang, 2010; Li, 2012; Dong et al., 2012; Luo and Li, 2013; Pan and Huang, 2009; Wang, 2014）. China, following U.S. and Canada, has become the third country realizing commercial development of shale gas.
