Catalytic hydropyrolysis for highly mature Carboniferous source rocks in the northern Xinjiang

  • 摘要: 针对新疆北部石炭系高演化烃源岩常规索氏抽提物含量低的特点,开展加氢催化裂解实验,对比分析两者的生物标志化合物特征,提高烃源岩的沉积背景及母源特征研究的可靠度。结果显示应用氢解产物的正构烷烃和甾烷化合物指示母质来源效果更好。浅部泥岩的正构烷烃呈nC18nC22-24的双峰型分布,表明远洋水生浮游动物的贡献大,而深部泥岩呈主峰碳为nC18-nC24的单峰型分布,指示以低等菌藻类水生生物贡献为主;抽提物中C27和C29规则甾烷含量相当,指示混合母质来源,而氢解产物中规则甾烷以C29为主,明确指示单一的母质来源。此外,氢解产物中含有更加丰富的βα-莫烷及ββ-升藿烷系列化合物,丰富了烃源岩的母质信息。研究明确石炭系烃源岩发育于较还原的沉积环境,优质烃源岩主要分布在下段,以菌藻类等单一的水生生物为有机母质来源,具备良好的生烃的背景及物质基础。实验也进一步证实氢解实验能够获取更多的生物标志物信息,对常规抽提方法是一种有益的补充。
