With the rapid development of economic globalization , the contradiction between supply and demand for energy in the world is becoming prominent .The conventional energy already cannot satisfy human needs and uncon-ventional energy exploration and development is imminent .Shale gas is unconventional natural gas , and it exists in the mud, shale or high carbon mud, shale as adsorption or free state.It is characterized by clean and enormous re-serves .The United States and Canada has made the successful commercial exploitation of shale gas , which effective-ly relieves the contradiction between supply and demand of conventional energy sources .Through comparing the geo-chemical condition of mud and shale formations in China with that of five shale gas system in United States , we can make conclusion that the initial shale gas yield of two sets of shale in southern Sichuan basin can match with the Devonian Ohio shale gas of Appalachian basin in the United States .It is believed that China has considerable shale gas reservoir .In recent years , China has being actively made some prospecting and exploration of shale gas .But the lack of core technology , singleness of investment , and poor infrastructure restrict the commercial exploitation of shale gas in China .% 美国、加拿大页岩气商业开发的成功，有效缓解了常规能源的供需矛盾。通过中国泥、页岩地层、地球化学条件与美国五大页岩气系统对比得出仅四川盆地南部地区两套页岩气的初始产量就与美国阿帕拉契亚盆地泥盆系Ohio页岩气相媲美，推测中国的页岩气藏有着相当可观的储量，开采前景广阔。近年来中国也在积极勘探开发页岩气，但核心技术缺乏、投资主体单一、基础设施落后等制约着中国页岩气的商业化开采。
