Abstract: Because of Yizheng orogeny in Late Cretaceous and Wubao orogeny during Himalayan movemenent of Cenozoic era, delta-shallow lake facies system in Fanzhuang was deposited by rifting and rise of sedimentary base level in Jinhu depression. Because of biotic classic limestone, beach bar and distributary mouth bar with thick sand and better physical property, which lies on the
top of sedimentary layers, and being close to oil source rock,they are the beneficial reservoirs. By hierarchy analysis, tentypes of architecture elements have been recognized in delta-shallow lake facies system. On the horizontal section , there are two models of architectural elements stacked form. On the verti-cal section, there are three models of architectural elements stacked form.

Key words: delta, sedimentary characteristic, sedimentary microfacies, reservoir architecture element, Sube Basin
