中国工程院院士胡文瑞近日在“2013国际页岩气大会”上表示,2012年我国三类非常规天然气产量445亿立方米,未来一至两年可能占到我国天然气生产的半壁江山。数据显示,2012年我国三类非常规天然气产量445亿立方米。其中致密气(也称低渗透天然气)去年产量达320亿立方米,净增长64亿立方 Hu Wenrui, academician of the Chinese Academy of Engineering, recently said at the 2013 International Shale Conference that the output of the three types of unconventional natural gas in China will reach 44.5 billion cubic meters in 2012, accounting for half of China’s natural gas production in the next one to two years in 2012. Data show that in 2012 China’s three types of unconventional natural gas production 445 billion cubic meters. Tight gas (also known as low-permeability natural gas) produced 32.0 billion cubic meters last year with a net increase of 6.4 billion cubic meters
