This paper analyzes the evolution of the palaeostructure in the Yanshan period in Sichuan Basin by palaeo-geotemperature.  The main structural development of the Yanshan movement is from Late Jurassic to Early Cretaceous, and eventually formed the tectonic framework of three paleo-uplifts and three palaeo-depressions in Sichuan Basin. This tectonic framework is not only conducive to petroleum accumulation, but also has an important effect on forming the continental red-bed secondary gas reservoir.
