| 摘 要： | 运用镜质组反射率、袍子体荧光参数、生物标志物参数详细研究了三塘湖盆地中生界烃源岩的有机质热演化特征及演化阶段。研究表明镜质组反射率是该区有机质热汪化最可靠听成熟度参数，孢子体荧光参数是重要的热演化指标，生物标志物参数是有效的热演化指标。三塘湖盆地有机质总体热演化水平较低，且在横向和纵向上存在明显的差异。该区的有机质热演化具有明显的阶段性，运用成熟度参数将其划分为未成熟和成熟两个阶段。

| Abstract: | Using vitrinite reflectance,fluorescence parameters of sporinite, biomarker parameters, the characteristic and stage of thermal maturity of Mesozoic organic matter in Santanghu Basin were studied in detail. The results show that vitrinite reflectance is the most reliable maturity parameter for the thermal maturity; the fluorescence parameters of sporinite are important thermal maturity indicators, biomarker parameter are effective maturity indicator. Generally, the mesozoic organic matter has a low thermal evolution in Santanghu Basin, which has clear difference not only in lateral,but also in vertical. The thermal evolution of organic matter in the area has obvious stage and can be divided into two stages of unmature and mature according to the parameters of maturity. |
