本文对中国苏北油田的高压地层原油中油溶气态烃类的组成因素进行了分析。对沼气发酵液中低分子挥发性脂肪酸脱羧所形成的烃类气体组成作了对比;对某些反应式进行了热力学计算,对甲烷和二氧化碳的碳同位素组成进行了分析对比。最后提出石油烃类气体不是热解或干酪根热降解形成。而是生物脱羧反应形成。这种生物反应,不是目前人们所进行的人工发酵沼气的生物化学反应,而是在沼气发酵以后所进行的生物化学反应。
In this paper, compositional factors of oil-dissolved gaseous hydrocarbons in high-pressure stratum crude oil in North Jiangsu Oilfield are analyzed. The composition of hydrocarbon gas formed by the decarboxylation of low molecular weight volatile fatty acids in biogas fermentation broth was compared. The thermodynamic calculations of some reaction formulas were carried out, and the carbon isotope compositions of methane and carbon dioxide were analyzed and compared. Finally, it is proposed that petroleum hydrocarbon gas is not pyrolyzed or formed by thermal degradation of kerogen. But the biological decarboxylation reaction. This biological reaction is not the biochemical reaction of man-made biogas currently carried out by humans, but rather the biochemical reaction carried out after biogas fermentation.
