Abstract: The principle, methods and some problems for application of Homogeneous temperature of fluid inclusions in calculating denuded strata thickness are systematically elaborated in this paper. The detailed application is ilustrated by the examples of recovery of the denuded strata thickness in Well 4-1-1 of W enzhou depression in Donghai basin and Well Lunnan-1 in Tarim basin. The results show that the erosion thickness of E2 stratum in Well 4-1-1 is about 1 900-2 050m, while that of Ordovician unconformity in Well Lunnan-1 about 2 600m. The study reveals that the method for recovery of denuded strata thickness is valid and applicable.
