摘要:
下刚果盆地深水区的油气显示出了海相原油的特征,盐上海相烃源岩开始受到关注。通过对下刚果盆地海相烃源岩地球化学资料分析,综合评价了盐上4套海相烃源岩的地球化学特征和生烃潜力,研究了其成因并划分了成因类型,同时探讨了不同成因类型烃源岩发育的主控因素。结果表明:下刚果盆地盐岩层之上发育海相烃源岩,有机质丰度中等—好,干酪根类型为Ⅱ、Ⅲ型,成因上以海相内源型和海相混合生源型为主;盆地海相烃源岩整体在3500m左右深度进入生油窗,成熟的海相烃源岩是下刚果盆地深水区油气的重要来源之一;由于上升洋流、缺氧环境(大洋缺氧事件)和古河流的作用,以及海洋、河流两种地质营力此消彼长的关系,自晚白垩世至中新世,盆地沉积环境从海湾变迁到受河流作用逐渐加强的开阔海洋,有机质来源从以海洋有机质为主过渡到河流携带来的陆源有机质比例加重,直到以陆源有机质为主;海陆二元有机质输入量的相对变化和海洋沉积环境的变迁从根本上决定了海相烃源岩的特征。
