| 摘 要： | 对目前表征海相烃源岩有机质成熟度的几个重要指标（镜质体反射率，沥青反射率，镜状体反射率、动物有机碎屑反射率及牙形刺色变指数等）进行了探讨与对比，并在总结它们各自优缺点的基础上，提出了选择海相烃源岩有机质成熟度评价指标的原则，进而提出牙形刺相对荧光强度（Ｉ５４６）是表征海相烃源岩有机质成熟度的良好指标，其具有较广泛的适用性。

| Abstract: | The author comparatively analyzed and compared some present important indicators(vitrinite reflectance,reflectance of solid bitumen,reflectance of vitrinite like maceral,reflectance of organic fragment such as graptolite,chitinozoan and scolecodont,color index alteration of conodont,etc.)with reference to the degree of maturation of marince hydrocarbon source rocks;on the basis of sum up their advantage and disadvantage,the author suggested the principle of selection to the organic maturation indicator of marine hydrocarbon source rocks;still further,the relative fluorescence intensity(I 546 )is suggested and regarded as a good indicator of determining the degree of maturation of marine hydrocarbon source rocks in this paper.The relative fluorescence intensity is well suitable to determine the degree of maturation of marine hydrocarbon source rocks lack of vitrinite. |
