利用镜质体反射率 (Ro)资料反演热史是否存在多解性取决于所采用的热流演化模型。采用目前常用的线性或指数模型 ,用 Ro 作为检验标准 ,通过地史与热史的联合模拟 ,能够对持续沉降升温的含油气盆地的热史进行反演。Ro 不仅与温度及受热时间有关 ,而且与地层压力和镜质体的类型等因素有关 ;用 TTI- Ro 法恢复烃源岩热演化 ,应当进行压力校正和氢指数校正 ,文中提出了具体校正方法
The use of vitrinite reflectance (Ro) data to invert the thermal history depends on the evolutionary model of the heat flux used. By using the commonly used linear or exponential model and using Ro as the test standard, the thermal history of petroliferous basins that are continuously subsided and heated can be retrieved by the joint simulation of geo-history and thermal history. Ro is not only related to temperature and heating time, but also to formation pressure and the type of vitrinite. TTI-Ro method can be used to recover the thermal evolution of source rock, and pressure correction and hydrogen index correction should be carried out. A specific correction method
