浅谈天然气气藏无机成因

油气有机成因说的发展日趋成熟,无机成因说则几经挫折。随着地质勘探的不断深入和资料的不断积累,认为虽然有机成因油气资源占据着主导地位,但也不能排除存在着无机成因的油气资源。通过研究烷烃气和二氧化碳的死亡温度,说明在高温的地球深处有无机成因气存在。对无机成因气形成的构造地质条件、物理化学条件和成藏条件进行了分析,侧重讨论不同于有机成因气的常规控制条件的特殊方面,并对无机成因气和有机成因气的成藏条件作了比较分析。

A Brief Talk About the Inorganic Origin of Inorganic Gas Pool

When the organic origin theory of gas and oil reservoir has been adopted by more and more specialists,the inorganic theory was developing very stagnantly.Along with the accumulation of data of geological exploration,it is accepted that although organogenic gas and oil resource occupied the dominant rule,anorganogene gas and oil resource could not be blown off.through the research of the dead temperatures of alkane gas and CO2,It is expounded that there is abiogenic gas in the high temperature deep places of the earth.This paper has analyzed the tectonic environment,gas-source formation,migration pathway and forming condition of inorganic gas pool,The special aspects of inorganic gas pool are discussed which are different from the organic.and the forming conditions of inorganic gas pool are compared with those of the organic.
