关于无机生油理论的思考

THINKING OF INORGANIC ORIGIN THEORY ON PETROLEUM

本文讨论了干酪根热解理论的困惑，论述了沥青、干酪根中Ｐｂ－Ｓｒ－Ｎｄ同位素的新证据，Ｐｂ－Ｓｒ－Ｎｄ同位素数据不支持沥青与干酪根同源，塔里木盆地、准噶尔盆地的沥青更多来自下地壳与上地幔，而原油中有机硅化合物的发现更进一步证实了它们更可能来自地壳深部，通过无机反应合成而生成。本文还提出有机质（及煤）加深部无机氢气的液化（或汽化）的生油（气）假设。本文指出，碳同位素作为油气物源判识需慎重对待。今天面对油气勘探的严峻局势，需重新认识油气无机生成理论。

This paper,on the basis of the puzzling kerogen pyrolysis theory,discussed Pb Sr Nd isotopic data in the bitumen and kerogen.Pb Sr Nd isotopic data don′t support the theory which petroleum (bitumen) derived from kerogen.The bitumen in the Tarim basin was from the lower crust but the bitumen in Karamay was from the upper mantle.The discovery of organic silicon compounds in the oils shows that the oils might be synthesized by inorganic interaction in deeper crust or upper mantle.This paper presents an oil (gas) generation hypothesis of organic matter plus inorganic hydrogen.The uncertainties of carbon isotopes showed that carbon isotope is not a reliable tracer.At present,inorganic petroleum theory can be applied to the further petroleum exploration.
