The Characteristics and Significance of Biomarker Compounds in the Amushan Formation Hydrocarbon Source Rocks in Manghanchaoke Region, Yin’e basin

摘要:
常规的烃源岩评价指标是针对钻井岩心样品制定的，对露头样品利用通常的评价参数进行有机质丰度、类型和成熟度等评价，不能有效反应盆地覆盖区烃源岩的真实情况，影响烃源岩生烃潜力的评价。笔者通过对银额盆地芒罕超克剖面石炭系阿木山组烃源岩正构烷烃、异构烷烃、萜烷类、藿烷类和甾烷类等生物标志化合物特征的综合评价，明确芒罕超克剖面阿木山组烃源岩原始沉积时期水体较深，沉积环境是还原–氧化环境，且以还原环境为主，有机质富集属“生产力模式型”；有机质主要来源于藻类和浮游生物等低等水生生物，烃源岩处于成熟−低成熟阶段。芒罕超克地区阿木山组烃源岩生物标志化合物系统研究对客观评价银额盆地阿木山组烃源岩的生烃潜力具有重要的作用。
Abstract:Conventional evaluation indexes of source rocks are developed for drilling core samples. The abundance, type and maturity of organic matter of outcrop samples are evaluated by using conventional evaluation parameters, which cannot effectively reflect the real situation of source rocks in the overlying area of the basin and affect the evaluation of hydrocarbon generation potential of source rocks. Based on the comprehensive evaluation of the characteristics of n-alkanes, iso-alkanes, terpenes, epiphanes and steranes of the carboniferous Amushan Formation source rocks in the Manghan Chaoke Section of Yinye Basin, it is clear that the water body of the source rocks of the Amushan Formation in the Manghan Chaoke section was deep in the original sedimentary period, and the sedimentary environment was reductive and oxidizing, and mainly in the reducing environment. Organic matter enrichment belongs to "productivity model". The organic matter mainly comes from algae, plankton and other lower aquatic organisms, and the source rock is in the mature to low mature stage. The systematic study on biomarkers of source rocks of Amushan Formation in ManghanChaoke area plays an important role in the objective evaluation of hydrocarbon generation potential of source rocks of Amushan Formation in Yinye Basin.
