Abstract：There are many scale-different sand-gravel body that developed in downdropped block of Chengnan great fault. The paper used 3-D visualization technique,seismic attributes technique and coherent analysis technique to analyze and predict the time and space distribution of sand-gravel fans,used logging-constrained inversion technique and time-frequency analysis technique to describe the single sand-gravel fan and determined the space distributed feature of 6 paleo-gulches of palaeogeo-morphology in the study area and their corresponding more than 10 sand-gravel bodies such as Cheng 913 etc.，preliminary forming the predicting and describing series of sand-gravel body, that realized high-efficient exploration and development of sand-gravel fan reservoir and resulted in good exploration benefits.
