Big reservoir body becomes the target of deepwater oil and gas exploration, because the deepwater oil and gas exploration has some characteristics, such as greater risks and higher investment. Central canyon, which comes from Yinggehai basin and pass through Qiongdongnan basin and enter into the Xisha trough, lies in the deepwater area of Qiongdongnan Basin and is mainly formed at 10.5 Ma, 5.5 Ma and 4.2 Ma. With an area of more than 50 000 km², central canyon can be a target of deepwater oil and gas exploration. In order to conduct the prospect for central canyon, this paper has analyzed the shape and control factors of levee-overbank deposited in the central canyon by using 3D seismic profile and RMS attribute. After that, the sediment model is summed up and the foreground of prospect is analyzed.oft-com:office:office" />
