中国页岩气开发的实质性突破

页岩气是指吸附在页岩中的天然气或自生自储在页岩纳米孔隙中连续聚集的天然气。新世纪以来,美国发生的页岩气革命影响了世界油气资源格局;中国的非常规油气储存量非常可观,是世界上具有页岩气可采储量最大的国家;但页岩气地质条件、水平钻井、分段压裂等技术储备和页岩气管理经验等还面临很大挑战。近年来,中国大力推进页岩气的开发利用,中石化、中石油和延长油田三家公司在示范区块开发的成功,以及短时间内在勘探开发方面取得的技术突破,标志着中国页岩气的开发已取得了实质性突破。但中国今后是否采取页岩气开发对多元资本开放的模式,还需要进一步研讨。

New stage of the development of shale gas in China

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.
