摘　　要：盆地古地温场的演化史是盆地有机质向烃类转化以及烃类保存或变迁的决定性控制因素之一。本文从演化史的角度分析了控制盆地地温场分布的多种因素，给出了以镜质体反射率为依据的古热流反演方法原理和以热传导热对流方程为基础的古地温场的正演模拟方法及数值解法。最后给出在新疆塔里木盆地和广西十万大山盆地的应用实例。The evolution history of the palaeogeotemperature field of a basin is one of the decisive factors which control the process in which organic matter turns to hydrocarbon and the hydrocarbon preserves as well as migrales. This paper analyses many factors which decide the distribution of the palaeogeotemperature field of a basin from the view of evolution history, presents the method of inversion of thermal flux based on vitrinite reflectance, and provides forward modeling method and numerical approach of the palaeo geotemperature fiesd based on thermal conduction and convection equation. Applications to Talimu Basin in Xinjiang and Shiwandashan Basin in Guangxi are presented at the end of the paper.
