摘要

The research of tectonic stress field is theoretical important and practical significant for petroleum migration and accumulation, reservoir characteristics description and crack formation analyses. The widely used finite element analysis software （ANSYS） was applied to simulate tectonic stress field of the end of Middle Ordovician, Middle Devonian, Triassic and Neogene, based on the characteristics and evolution history of faults combined with well drilling data in the Tazhong uplift, with emphasis on the Middle-Lower Ordovician limestone. The result indicates that the maximum compressive principal stress, which was affected markedly by the eastern strike-slip fault named Cherehen-Xingxingxia, presents strip-shaped and low-value distribution along faults zone in uplift area.
