摘要
通过天然气甲烷及同系物碳同位素研究,将天然气分为油型气和煤成气。采用轻烃及碳同位素方法对成熟度综合分析,认为该区天然气主要形成于深成作用阶段(成熟—高成熟期)。气源对比证实,该区油型气与二叠系源岩具有亲缘性。本文还就该区天然气可能发生的次生变化进行了讨论。
Two types of natural gas from Fukang Fault Belt have been classified through examining contained methene and iso—series carbon isotopes: oil—forming gas and coal—forming gas composite analyses for their maturites were made using methods of light hydrocarbons and carbon isotopes and indicated that gas of this region was mainly formed clur- ing a plutonic phase (a mature to high mature period). It verified from correlation of gas soure that they are of affinity between oil—forming gas and permian oil source rock here. this paper also discussed the potential secondary changes occured in gas of this region.
