According to interpretation of seismic data in the western Kuqa Depression, we analyze the style of salt-related tectonics. We analyze the formation stage of salt-related tectonics through balanced section. The formation stage can be divided into two stages: the stage before the end of E1-2 deposition, and the end of the Himalayan movement. We make two manual wellsand to model their source rock's maturity history by BasinMod 1-D of the PRA company. Through analyzing the matching of the formation stage of salt-related tectonic traps and the stage of hydrocarbon generation, we consider that there can be good hydrocarbon reservoirs in Kelasu tectonic belt since the formation stage of the paleotectonics traps match the stage of hydrocarbon generation in the Kelasu tectonic belt and Baicheng sag. However, these hydrocarbon reservoirs were destroyed seriously at the end of the Himalayan and formed irreducible hydrocarbon reservoir and secondary hydrocarbon reservoir after they were regulated and destroyed by tectonic movement. The trap below thick salt layer can be gas reservoir near the Baicheng sag. The formation stage of paleotectonics traps in the Qiulitage tectonic belt match the stage of hydrocarbon generation in the Baicheng sag and the formed hydrocarbon reservoirs were conserved well. Above salt layers, there can form faulted anticline oil reservoir or anticline oil reservoir. There can form gas reservoir below thick salt layer.
