原始大气的演变与石油天然气的形成

THE EVOLUTION OF THE PRIMITIVE ATMOSPHERE AND THE FORMATION OF PETROLEUM ANDNATURAL GASES

关于石油天然气的形成 ,有机成因说目前已被普遍接受。但天文学家发现宇宙中存在大量天际有机分子 ,其中甲烷是天然气的主要成分 ,这就说明有机物并非是石油天然气的唯一来源 ,石油天然气的形成可能十分复杂 ,是多种因素综合的结果。本文试图从原始地球的原始大气组成入手 ,简要分析其演化历程以及可能形成的有机物 ,重新探讨石油天然气的形成。

As for the origin of petroleum and natural gases, the hypothesis of organic origin has been commonly accepted. However, astrologists have found that there exist large quantities of celestial organic molecules in the universe, with methane as the predominant component of natural gases. This indicates that organic matter is not the only source of petroleum and natural gases. The formation of petroleum and natural gases may be very complicated and seems to be the result of combination of a variety of factors. This paper tempts to briefly analyze the process of evolution of primitive atmospheric components and the possible mechanism of formation of organic matter so as to give an insight into the formation of petroleum and natural gases.;
