摘要
通过对准东石炭系沉凝灰岩地化特征分析,确定沉凝灰岩为一种与火山活动有关的新型烃源岩,并对取自不同井的沉凝灰岩的生物标志化合物和饱和烃总离子流图进行比较,认为沉凝灰岩具有3种不同的成烃特征.本文研究成果为沉凝灰岩这种新型烃源岩的研究奠定了基础.
Based on a statistical analysis of the geo-chemical features of Carboniferous hydrocarbon source rock in the eastern part of Junggar Basin,it is held that sedimentary tuff is a new type of hydrocarbon source rock related to volcanic activity.The study on the characteristics of its biomarkers and total ion chromatograms(TIC) of saturated hydrocarbon shows that the sedimentary tuff is of three characteristics of hydrocarbon generation.The research result in the paper can provide the foundation for the research of this new type of hydrocarbon source rock.
