| 摘 要： | 镜质体反射率（Ｒｏ）与其生烃率有关，因此，由Ｒｏ应可求取其生烃率；同时，在求取了镜质体成烃反应动力学参数之后，若已知其受热史，则可计算出镜质体的生烃率；反过来，若已知镜质体的生烃率，应可反推其受热史。基于这一基本原理，本文在建立和标定镜质体成烃反应动力学模型的基础上推导了可将其应用于存在着抬升、剥蚀和古地温非线性变化等复杂地质条件下热史恢复的原理模型，结合海拉尔盆地海参７井的实测Ｒｏ值，有效地恢复了其古热史

| Abstract: | The vitrinite reflectance ( R o) is related to its hydrocarbon generation ratio, therefore, the hydrocarbon yielding could be calculated from its R o value. Meanwhile, having calibrated the reactive kinetic parameters of hydrocarbon generation of vitrinite, we can calculate its hydrocarbon yielding if its paleo heat history is known. On the contrary, if when the hydrocarbon yielding is known, it is possible to deduce the heating history it experienced.Based on this basic principle, the kinetic model of hydrocarbon generation of vitrinite is constructed and calibrated, and the theoretical model of restoring paleo heat history, which can be used in sophisticated geological conditions such as in a region once undergone uplift , erosion or non linear variation of paleo teperature, is set up.Combined with measured R o values of practical samples, the paleo heat history of Haican-7 Well is recovered effectively. |
