对天然气水合物甲烷无机成因的初步探讨

ll researches about Natural Gas Hydrate are built on the basis of the source of gas accumulation. As a result, the source of methane becomes one of the most important issues. At present, most scholars tend to believe organic source. However, the authors believe that inorganic source also exists and it should be in-depth studied. In this paper, the authors focus on the mechanism of inorganic source. Preliminary argumentations about inorganic source of methane are demonstrated from geological structure, geochemical character of void, isotopes, and microorganism. As a result, the inorganic source of methane is reckoned. At the end of this paper, based on the inorganic source of methane, the difference value between acidolysis hydrocarbon method and headspace method is analyzed.
