| 摘 要： | 下古生界缺失高等植物来源的镜质组,其有机质成熟度的确定一直是油气源岩评价的难题之一。基于对含笔石页岩的反射光显微镜观察和低成熟度含笔石页岩与煤共置的热压模拟实验,研究了下古生界海相页岩笔石表皮体的光性特征及其热演化规律,探讨了笔石表皮体随机反射率作为有机质热演化参数的可行性。下古生界海相页岩非粒状笔石表皮体呈条带状顺层或者碎片状产出、颗粒较大,光学特征类似于镜质组,适合于测量反射率。非粒状笔石表皮体随机反射率■换算为等效镜质组反射率■的关系式为■。采用笔石表皮体随机反射率分析了上扬子地区东部五峰组—龙马溪组页岩的有机质成熟度分布特征,认为非粒状笔石表皮体随机反射率是一个实用的下古生界烃源岩有机质成熟度指标,为确定下古生界有机质成熟度提供了一种可信的解决方案。
