Geochemical characteristics of light hydrocarbons in condensate oil from the southwestern Huizhou of the Pearl River Mouth Basin

  • 摘要:

    惠西南地区是珠江口盆地珠一坳陷重要的原油富集区, 但近年来在新近系珠江组上段和古近系恩平组、文昌组以及基岩潜山储层中陆续发现了凝析油气。利用全油气相色谱和饱和烃色谱-质谱分析技术对凝析油样开展了轻烃和生物标志化合物地球化学特征分析, 探讨了惠西南地区凝析油的成因。研究表明: 轻烃组分特征、C7异构烷烃、环烷烃及正构烷烃和生物标志化合物特征均指示H6-1构造凝析油来源于半深湖-深湖相文昌组烃源岩, 为腐泥型烃源岩在相对高成熟阶段(Ro处于1.2%~1.3%)生成的凝析油; H1-1构造凝析油来源于浅湖沼泽相恩平组烃源岩, 为偏腐殖型烃源岩在相对低成熟阶段(Ro处于0.9%~1.1%)生成的富低碳数烷烃油气; 揭示了惠西南凝析油的形成受到烃源母质类型和热演化阶段的双重控制。研究结果为富油生烃凹陷凝析油气勘探潜力评价分析提供了地球化学依据和支撑。
