摘要
目的研究焉耆盆地煤系烃源岩有机显微组分组成特点及其生烃机理。方法运用有机岩石学研究方法,分析盆地侏罗系烃源岩显微组分及其与生烃潜力的关系,探讨烃源岩显微组分中主要生烃贡献者。结果盆地煤岩中显微组分表现出富镜质组-惰性组、贫壳质组+腐泥组的特点;泥岩的显微组成表现出贫惰性组、富镜质组-壳质组+腐泥组的特点,富氢的显微组分是成烃的物质基础。结论盆地的主要生烃组分为基质镜质体B、角质体、小孢子体和矿物沥青基质。
Aim To study the organic maceral grouping features of coal measures source rock and hydrocarbon generation mechanism for Yanqi Basin.Methods Analyzing the maceral of Jurassic source rock and its relation to micro composition based on petrology and discussing major factor of hydrocarbon generation.Results The micro composition of ingredient has the feature of rich vitrinite-inertinite,lean exinite,and humulite while mud rock has the feature of lean inertinite,rich vitrinite-inertinite exinite,and sapropel.Conclusion Major compositions of hydrocarbon generation are Degradinite B,cutinite,microspore,and mineral pitch substance.
