Abstract: Sequence and system tract were divided in Jurassic, Cretaceous, Paleogene and Jidike formation of Neogene in Tabei uplift based on sequence stratigraphy principle and its study method. Four sets of reservoir rocks, i. e. sandstone at the bottom of Jurassic, extensive Cretaceous sandstone, sandstone at tlie bottom of paleogene and sandstone at the bottom of Jidike formation, and two sets of salt-gypsum caprocks, i. e. Lower Paleogene salt-gypsum bed and salt-gypsum bed of Jidike formation were emphaticliy studied, including determination of their extent, proper interpretation of their sedimentology, valid assessment of reservoir-caprock assemblage, and selection of favorable exploration area and target.

Key words: Tarim basin, Mesozoic, Cenozoic, Sequence stratigraphy
