Abstract:To research the approaches of seismic sedimentology on deep glutenite bodies were discussed,guided by geological laws and seismic sedimentology theory,and constrained by core and logging data,fourth-order se-quences of the upper Es4in the eastern section of northern zone of Dongying sag were analyzed by using 90° phase shift and stratal slicing technology.The research procedure for deep glutenite bodies was established.The sedimentary facies types were confirmed and their distribution and evolution were analyzed.The results show that the key technologies of seismic sedimentology are suitable for interpretations of deep glutenite bodies and have significant advantages in interwell sedimentary facies. The upper Es4has a complete third-order se-quence.It can be divided into 5 fourth-order sequences.In the sedimentary period of upper Es4,nearshore sub-aqueous fan,slump turbidite fan,and lacustrine sedimentary facies were developed in the eastern section of northern zone of Dongying sag.The nearshore subaqueous fans were distributed near the Chennan Fault and the retrogradation depositional system was well developed in the vertical direction.
