非生物成因气与松辽盆地深层气:综述与思考

Abiogenic Gas and the Deep Gas in the Songliao Basin:An Overview and Consideration

结合封闭体系费—托合成实验,综述了已知非生物气苗和松辽盆地深层天然气化学成分及碳氢同位素组成特征与进展。对非生物气和松辽盆地深层天然气研究现状进行了思考。建议关注非生物气化学组成特征和实验条件的探索,加强热力学平衡体系和气藏后期地质过程的研究,综合研究松辽盆地深层天然气的成因。

The characteristics and the research advances of the chemical components and carbon-hydrogen isotope compositions of known abiogenic gas seepages and the deep gas in the Songliao basin are reviewed, combined with our Feisch-Tropsch synthesis in a close-system. The abiogenic gas and the deep gas in the Songliao basin are reexamined in this paper. Attentions should be drawn to the chemical components and the experimental condition. It is suggested that the thermodynamics, thermodynamic equilibrium, post-genetic processes be focused on in the future. Moreover, an integrated study on the deep gas in the Songliao basin needs to be performed to investigate the origin of the deep gas.
