摘　　要：运用不同方法对比研究德惠断陷火石岭组天然气组分。研究中通过天然气碳同位素和轻烃族组成验证德惠断陷火石岭天然气类型;利用轻烃指纹研究并未区分出火石岭组和沙河子组泥岩的轻烃指标;通过聚类分析与秩和检验证明了火石岭组和沙河子组泥岩轻烃指纹参数并无差别;通过轻烃指标交会图分析了火石岭组天然气与沙河子组泥岩和火石岭组泥岩的亲缘性。最后推断火石岭组和沙河子组泥岩混合形成德惠断陷火石岭组天然气气源。In this paper different methods are discussed to research the component of natural gas in Huoshiling formation,Dehui fault depression. The analysis of light hydrocarbon group composition and carbon isotope proved that the type of Huoshiling natural gas is a mixture of coal- type and oil- type gases. The light hydrocarbon fingerprint can＇t distinguish between mudstone light hydrocarbon indicators of Huoshiling formation and mudstone light hydrocarbon indicators of Shahezi formation. Then cluster analysis and rank- sum test are used to prove that there is really no difference between light hydrocarbon indicators of Huoshiling formation and mudstone light hydrocarbon indicators of Shahezi formation. Through light hydrocarbon index crossplot shows that natural gas of Huoshiling formation have familiarity with mudstone of Huoshiling formation and Shahezi formation. So these methods shows Huoshiling natural gas comes both from the source rock of Shahezi formation and Huoshiling formation.
