Abstract:
Shale gas is natural gas that is found trapped within shale formations. Shale gas has become an increasingly important source of natural gas in the United States since the start of this century,and interest has spread to potential gas shales in the rest of the world. In 2000,shale gas provided only 1% of U.S. natural gas production; by 2010,it was over 20%; and the U.S. government’s Energy Information Administration predicts that by 2035,46% of the United States’ natural gas supply will come from shale gas. Though China is estimated to have the world’s largest shale gas reserves,due to complex geology,innovation problem and market policy,it is a big challenge for us. This paper reported quick and great advance that have been taken by Sinopec in Fuling,Sichuan Province,by CNPC in Changning-Weiyuan,Sichuan Province,and by Yanchang in Shaanxi Province. The paper estimated that the developments of shale gas in China have already come to stage of market business,but a lot of problems still remain debate.
