The south Shangdian fault block is located in the Shangdian Shangdian Oilfield of dongying Depression of Shengli Oilfield of Shandong Province. The Dongying Formation of Paleogene is well defined by unconformity or discontinuous surface both at its top and bottom. Within this Formation, some delta deposits were developed due to lacustrine transgression. Based on the drilling log and seismic studies of over 100 wells, over 70 sections of single well and correlations of 14 sections in the Shangnan faulted block, the sedimentary facies of the Dongying Formation are well studied. Mthan 30 casting-dot figures of sedimentary microfacies and lithofacies palaeogeographies are designed. The results show that in the Dongying Age, the environment of flourish rainfall, moist climate, abundant rivers and lake, and so on is favorable to developing lacustrine transgressive delta.Although the regional source areas, the Chengning uplift and the Luxi uplift, might play an important role in controlling the sedimentary envirenment and the sequence development,the local source areas,such as the Binxian arch and the Linfanjia arch also play an important role in the delta development. There were three evolutional stage of lithofacies palaeogeographies during Dongying Age , including the Early, Middle and Late Age . During the Early Age, the sedimentary environment of delta plain predominated. In the Middle Age, the destructed delta Was developed. In the Late Age, the foredelta was characterized.
