| 摘 要： | 近年在我国陆相地层中相继发现了一些含凝析油的天然气气藏,其成因为生物和低温热解作用形成。气源岩主要为腐殖型,埋深在3000m以内。位于低成熟带.气的成分以甲烷为主,δ～(13)C_1=-45‰～-55‰,δD_(CH)_4=-200‰～-263‰。我国中新生代地层发育,变质程度较低,具备生物一低温热解气成藏的有利条件。

| Abstract: | ??In recent years, a number of condensate-bearing gas reservoirs originating from biological activity and low-tempcrature thermolysis were successively found in the strata of continental facies in China. The source rocks buried in less than 3000m at the lower-mature zone mainly contain organic matters of humic type. The gas composition is mainly methane, ??13C1=-45??~-55??, ??DCH4=-200??~-263??. The lower metamorphic grade Mesozoic-Cenozoic strate developing in our country possess the favourable conditions to form biological activity and lower temperature thermolysis gas reservoirs. |
