壳源非生物成因烃类气研究进展

Progress in study on crust-derived abiogenic hydrocarbons

结合国外近几年的相关研究进展,系统总结了壳源非生物成因烃类气的形成机理及地质、地球化学特征,并分析了其成藏的可能性、可能成藏的有利地区以及研究前景。结果表明,壳源非生物成因烃类气不仅存在,而且分布较为广泛,研究前景也十分广阔。随着研究的深入,人们对非生物成因气,特别是壳源非生物成因烃类气的认识将会进入到一个崭新的阶段。

The study on the crust-derived abiogenic hydrocarbons was developed quickly in recent years at abroad. The forming mechanisms and geological and geochemical characteristics of crust-derived abiogenic hydrocarbons were summarized, and the possibility of forming reservoirs, the favorable zones and the correlative study prospect were analyzed. The results showed that the crust-derived abiogenic hydrocarbons existed indeed and also distributed widely. The foreground of research on them is broad, though many unknown fields still existed. As the studies go forward, the understanding to the abiogenic natural gas, especially to the crust-derived abiogenic hydrocarbons, will get a new step.
