Large shallow-water delta was found in the rift lacustrine basins based on the study of depositional systems, sedimentary characters and sedimentary modles of Es3s~Es2 formation in Niuzhuang subsag, Dongying sag. There are some differences between the shallow-water delta which can be found in the rift lacustrine basins and in the depression lake basins. The style of microfacies, the figure in the plane and the characters of sand bodies changed by phases, and this change is closely related to the system tracts. In the lowstand systems tract and regressive systems tract, the subaqeous distributary channel is the most common microfacies and the delta’s figure looks like the meandering river’s and the subaqeous crevasse splay can be found. The sand bodies are thick but poor continuity. However, in the transgressive systems tract and highstand systems tract, the most common microfacies is distributary-mouth bar and the figure looks like the leaf or the tongue. The sand bodies are thin but continuity. The form of the shallow-water delta is affected by paleoprovenance, paleotopography, paleobathymetry and palaeohydrodynamic. The change of system tract and water depth which caused by tectonic movement is the control factor of the delta’s evolution by phases.
