中科院院士、中国石油学会理事长贾承造在2009年3月26日北京召开的首届中国低渗透(致密)油气勘探开发技术研讨会上表示,预计中国油气产量中,低渗透油气所占比例将持续增大,中国未来油气产量稳产增产将更多地依靠低渗透油气。在中国油气产量构成中,低渗透油气产量的比例逐年上升 Jia Chengzao, academician of the Chinese Academy of Sciences and chairman of the China Petroleum Institute, said at the first seminar on low-permeability (tight) oil and gas exploration and development held in Beijing on March 26, 2009 that it is estimated that the proportion of low-permeability oil and gas in China’s oil and gas production will continue to increase Big, China’s future oil and gas output steady production increase will rely more on low-permeability oil and gas. In the composition of oil and gas production in China, the proportion of low-permeability oil and gas production has been increasing year by year
