Abstract: Based on the established sequence stratigraphic framework, the sedimentary evolution characteristics of the upper section of the fourth member of Shahejie Formation (Es4) in Linan Subsag of Bohai Bay Basin were analyzed through integrated utilization of core, well logging, mud logging, and seismic data. Combined with the activity analysis data of basin-controlling faults, the controlling effects of diverse paleogeomorphology on sedimentary systems and sandbody distribution were elucidated, and a tectono-sedimentary coupling model for the sedimentation period of sand group 2 in the upper Es4 sub-member was established. The results show that: (1) During the sedimentation period of sand groups 3 and 4 in the upper Es4 sub-member of Linnan Subsag, the climate was arid, primarily developing sedimentary systems of fluvial terminal fan. During the sedimentation period of sand groups 1 and 2, the climate gradually became humid, driving an evolution from fluvial terminal fan sedimentary to normal lacustrine sedimentation characterized by (fan) delta-shore shallow lacustrine beach-bar systems. (2) Paleogeomorphology in the study area control the distribution of sedimentary facies and sandbodies, which can be identified as four key patterns: broom-like faults, axial fault troughs, comb-like faults, and steep-slope parallel fault terraces. Axial fault troughs can serve as sand transport channels, guiding sandbody progradation along the trough axis. Syn-depositional fault-associated topography (comb-like faults, steep-slope parallel fault terraces, broom-like fault zones) provide significant accommodation space, controlling sandbody accumulation locations and defining favorable targets for sandstone reservoirs. (3) Tectonically, Linnan Subsag became the primary depocentre during the upper Es4 sub-member deposition due to subsidence driven by Xiakou and Linshang basin-controlling faults. Regionally, broom-like faults influenced sandbody migration via fault troughs towards the subsag in the north. Southwestern axial fault troughs served as a critical sediment pathway, promoting NE sand progradation. Comb-like faults controlled fan delta progradation and relative thick sandbody accumulation at fault-angle bases in Jiangjiadian area. Fan delta sediments developed at steep-slope parallel fault terraces in Wawu area are perpendicular to the boundary fault and exhibit retrogradational distribution. Sandbodies in Shanghe area have been influenced by alongshore currents, forming beach-bar systems.

Key words: paleogeomorphology, broom-like faults, axial fault troughs, comb-like faults, steep-slope parallel fault terraces, fluvial terminal fan, upper Es4 sub-member, Paleogene, Linnan Subsag, Bohai Bay Basin
