     According to outcrop investigation and well-logging identification, the sedimentary characteristics and distribution law of the alluvial fan in Kuche Formation of Neogene in Kuqa Depression were systematically studied with seismic and 3D electric method data, and the sedimentary models of the alluvial fan were obtained. The results of comprehensive research reveal that the scales of alluvial fans in the western region nearby well Bz1 and well Db1 are larger than those in the eastern region, and the tectonic movement is the main controlling factor. It is considered that there are two models of alluvial fans in Kuqa Depression, i.e. a model of single provenance of conglomerate, which reveals a long-term, stable and successional depositional process, and a model of multiple provenances of conglomerate, which is controlled by local structures.
