Abstract: Using three-dimension seismic and well-logging data，a study was conducted on the sequence stratigraphic characteristics of the middle sub-member of the third member of Paleogene Shahejie Formation in the Liangdong area of the Dongying Sag. The internal systems tracts，composition，structure，sedimentary characteristics，and spatial variation patterns of the sequences were analyzed. The results show that：（1）The middle submember of the third member of Shahejie Formation in the Liangdong area of the Dongying Sag can be divided into highstand systems tract（HST），falling stage systems tract（FSST），lowstand systems tract（LST），and transgressive systems tract（TST），reflecting a complete base-level change cycle. Due to the lateral variations in sediment supply and accommodation space，the main source area in the middle sub-member of Shahejie Formation developed a complete sequence. In contrast，on both sides of the main sedimentary area，the thickness of the systems tracts gradually thins，and shoreline migration characteristics are not obvious.（2）The FSST facies in the study area are dominated by delta front deposits，which can be further subdivided into microfacies such as underwater distributary channels and mouth bars，with some occurrences of gravity flow microfacies. The LST inherits the sedimentary characteristics of the FSST in its evolutionary sequence，mainly represented by a deltagravity flow system，but further extending towards the basin. The sedimentary center of the LST shifted westward compared to the FSST，indicating the long-distance progradation characteristic of the sedimentary system in the LST.（3）The strong activity of growth fault F1 in the study area controlled the distribution of sand bodies. The differential subsidence between the hanging wall and footwall of the fault caused changes in sediment supply and accommodation space，leading to variations in the geometric characteristics of the systems tracts and strati-graphic stacking patterns along the sediment source direction. In the hanging wall of the fault，where there is higher subsidence and greater accommodation space，the systems tracts are fully developed，and the sand-toshale ratio is the highest. In the footwall，with higher elevation，lower subsidence，and smaller accommodation space，the thickness of the HST and LST decreases significantly，and the sand-to-shale ratio is also relatively smaller.（4）The HST in the study area is composed of thick layers of dark mudstone and oil shale，which can serve as excellent source rocks. The deltaic and gravity flow sand bodies in the LST and FSST are the main reservoirs. The TST is characterized by widespread dark mudstone，which can act as a cap rock. The vertical arrangement of the systems tracts in the middle sub-member of the third member of Shahejie Formation forms a favorable source-reservoir-seal configuration.

Key words: sequence stratigraphy, fourth-order systems tract, underwater distributary channels, mouth bars and other microfacies, gravity flows, accommodation space, third member of Shahejie Formation, Paleogene, Liangdong area, Dongying Sag
