As an important part of continental rift lacustrine basin， the structural zones of the basin margin which are usually located close to the hydrocarbongenerating center， are important petroliferous belts in the continental rift lacustrine basin. In the Bohai Sea area， the structural styles of the Paleogene lacustrine basin margin can be divided into two types: extensional lacustrine basin margin and strike slipping lacustrine basin margin  and the former one  is further subdivided into the steep slope faulted  lacustrine basin margin， the gentle slope faulted lacustrine basin margin， the simple gentle slope lacustrine basin margin and the axial slope lacustrine basin margin. The extensional lacustrine basin margin is widely distributed in the large sags of the study area， while the strike slipping one is developed in the eastern area of the basin and is mainly controlled by the TanchengLujiang faulted belt. Due to the differences of the structural movements， the structural evolution of different lacustrine basin margins， the palaeogeomorphology，  the accommodation variation and the sedimentary base level changes are different. As a result， different lacustrine basin margins with different structural styles have different sedimentary sequence filling models. The analyses of the control of lacustrine basin margin structural styles on sequence filling are very important for reservoir delineation and prediction of lithologic traps.
