In this paper, the authors made multiple stratigraphic division of tectonic layers and lithostratigraphic study for the Cenozoic of the Qingdong sag using the materials of lithology, well logging,seismdata, palaeobiology and regional geology. The Cenozoic in the study area can be divided into two tectonic layers: the Paleogene and the Neogene to Quaternary. The Paleogene comprises Kongdian Formation, Ha-4 Member, Sha-3 Member, Sha-2 Member from bottom to top and without Sha-1 Member and Dongying Formation. The development characteristics of strata in the Qingdong sag are similar to the Dongying sag except the incompleteness in vertical stratigraphic succession. The analysis shows that the thickness and distribution orientation of the remnant strata changed greatly and regularly which reflects the differences of basin sedimentary filling and tectonic evolution in different geological times.
