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(成熟一高成熟期)。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。

Abstract: Two typea of natuzal gas from Fukang Fault Belt have been classified through examining contained methene and iso- serjes carbon isotopes:oil - forming gas and coal- forming gas composite analyses for their maturites were made using methods of light hydrocarbons and carbon isolopes and indicated that gas of this region was mainly formed cluring a plutonic phase (a mature to high mature period). lt verified from correlation of gas soure that they are of affinity between oil-forming gas and perrnian oil source rock here. this paper also discussed the potential secondary changes occured in gas of this region.

Key words: Fukang Fault Beit, gaseous gentie types, maturity, correlation of gas sources
