摘要

///Bohai Basin is characterized by tectonically-uniform block with steady and slow subsidence, which resulted in low-relief, low gradient, and high-stand lake-level depositional settings during the Neogene. Excellent reservoir-seal combinations and superb conditions are formed for the formation of hydrocarbon traps in the region. Cyclic depositions of shallow water deltaic system which were dominated by fluvial systems showed obvious lobe shape on contour maps and very good lateral connectivity between lobes. Therefore, the shallow water deltaic reservoirs still should be the focus targets for exploration for adding new reserves and increasing productions in this region.
