Based on the core, logging and well log data, integrated with available seismic interpretation results, in-depth study of sedimentary characteristics and sedimentary facies distribution of Jurassic in southeast depression of Tarim Basin is made, including the relations between sedimentary facies variation and tectonic evolution. The study shows that in Early-Middle Jurassic, Ruoqiang sag was a fault basin with alluvial fan and braided river delta deposits in Early Jurassic, braided river delta and lacustrine deposits in Middle Jurassic; in Late Jurassic, it became a downwarping basin dominated by fluvial deposit. Ruoqiang structural belt and Minnan structural belt are favorable areas for petroleum exploration.
