Abstract: The sedimentary facies of Carboniferous Bioclastic Limestone Member is mainly classified into shore and carbonate platform facies in Tarim basin. In the paper, two depositional models are established by comprehensive analysis: they are the clastic shore to carbonate platform model and the carbonate intraplatform model. Terrigenous clastic and mixed shore facies are mainly distributed in the north of Tarim basin. Evaporate platform facies are spread in the east of the 4 wells in middlTarim and in Qikuqiake area, and the best dolostone reservoirs are largely located there, too. In other areas the restricted and semi-restricted platform facies are distributed. At the end of the paper, we discuss the sedimentary facies evolution in Carboniferous Bioclastic Limestone Member.

Key words: Tarim basin, carboniferous, carbonate rock, sedimentary facies, sedimentary model
