| Abstract: | This paper presents the process of the formation and evolution of the distributary channel of delta ,quantitatively analyzes the morphological feature of the distributary channel and the feature of distribution of the sand body of delta ,studies the changes of grain size of the distributary channel ,the point bar and the splay ,and comparatively analyzes the change tendency of the ratio of width to thickness at the distributary channel and front sheet sands of the waterways and underwater.Above study,combined with the determination of characteristics of delta sandbodies,provides information for the practical application in production. |

| Keywords: | sand body of delta distributary channel crevasse splay ratio of width to thickness main stream point bar |
