天体演化与地球的无机烃——卡西尼号飞船带给我们的启示

The Evolution of Celestial Body and the Inorganic Hydrocarbons of the Earth——An inspiration from the Cassini Mission

陨石、彗星、月球、太阳系大行星及其卫星、宇宙广泛分布着石油烃化合物,土卫六的巨量的甲烷气、液态烃、黑色有机物就是十分典型的例子。根据行星地质学和地球演化史,探讨了地球无机烃存在的可能性。列举了国内外地球无机烃的生成模式:地球脱气模型(戈尔德、杜乐天)、地球吸积模型(欧阳自远)、费托地质合成模型(沃里沃夫斯基、萨尔基索夫、萨特马利)、多种成因的综合模型(张景廉)。介绍了张景廉等近10年来关于油气成因的研究成果:根据Pb,Sr,Nd同位素资料,可以对一些油田的成因进行判识,油气无机成因论不仅可解释中国大陆油气田的分布规律,而且可以对未来勘探靶区进行预测。卡西尼号飞船给我们的启示是:地球深部尚有巨大的油气储量,而按照油气无机成因论是可以寻找大油气田的。

The hydrocarbons are universally distributed in meteorite,comet,moon,major planets of solar system and their satellites and the universe.The existence of plentiful methane,liquid hydrocarbon and black organic compounds in the Sature＇s Satellite Six is a typical example.Based on the planetary geology and the evolution history of the Earth,the possibility of inorganic hydrocarbon in the Earth is discussed.Some models for the inorganic hydrocarbon generation of the Earth at home and abroad are introduced,which include the earth outgassing model proposed by Gold and Du Letian;the Earth absorption-accumulation model by Ouyang Ziyuan;Fischer-Tropsch model by Volivofski,Sarkisuv and Szatmari;multi-origin model by Zhang Jinglian.According to Pb,Sr and Nd isotopic data,the origin of some oilfields in China can be distinguished.By means of the inorganic origin theory of hydrocarbon,China＇s oil fields distribution regularity can be explained and the future exploration targets can be predicted.The inspiration from the Cassini Mission is that there are huge petroleum reserves to be explored in the deep Earth,and based on the inorganic origin theory of hydrocarbon,it is possible to find out some giant oil-gas fields.
