There are 9 obvious characteristics of delta progradation units developed in the middle part of 3rd member of Shahejie formation in Dongying depression, and the Dongying delta is shaped in wedge-S type and gradually prograded into the center of the depression, and the feature of progradation stage is remarkable. Based on abundant drilling data and high precision 3D seismic data, this study used a special method in this area to recover the paleo-geomorphology with quantification and high precision shoreline trajectory method, aiming at reconstructing the paleogeomorphology of the nine delta progradation units and revealing the controlling on sedimentation. The results show that, the overall paleogeomorphology characteristics of the middle part of 3rd member of Shahejie formation is gentle south and steep north, and the slope migrates westwards. Distribution and depositional style of sedimentary deposit are coupled well with paleogeomorphology: the delta deposit is mainly prograded gradually along the eastern and southeastern uplifts until the basin, which is affected by the source supply capacity and paleogeomorphology, the delta lobe extends westward along the slope; while in the deep depression area, the sedimentary facies is mainly consisted of semi-deep and deep lacustrine deposits. The sediment in the steeper slope front is prone to be instable and thus forming the turbidite sand body.
