天然气在中国大陆科学探索井的发现及其科学意义

中国大陆科学探索井中科1号井在476m、869m、l935m发现了有可能是深源气的CH4、C02和He的高异常，可以肯定地说，它们是非生物成因的气体，是无机成因气。在变质岩地区和层段发现的无机成因天然气有重要的科学意义，已成为油气无机成因说的佐证。建议中科l号井这一重大课题吸纳石油地质学家和地球化学家参与，使该井随钻取样和录井工作更为全面系统，兼顾无机油气勘探方面的探索与研究，积累宝贵的数据和经验，以利于我国油气勘探事业的发展。

Natural Gas Discovery in China＇s Continental Scientific Exploration Well and Its Scientific Significance

In Zhongke,1 Well,a China's continental scientific exploration well,discovered CH4,CO2 that were probably deep source gases and high anomaly of He at depth of 476 m,869 m and 1935 m,respectively. It is affirmed that they are non,biogenic gases,or inorganic genetic gases. These inorganic genetic gases discovered in metamorphic rock area and zone are of great scientific significance as demonstration or proof of hydrocarbon inorganic genetic theory. Therefore,this paper suggests that this major research subject of Zhongke,1 Well should attract petroleum geologists and geochemists to participate in,in order that logging,and sampling,while,drilling on this well become more systematic,giving attention to probes of two aspects for inorganic gas and oil exploration. The cumulative and valuable data and experiences are favorable for further development of China's petroleum prospecting causes.
