Abstract：Using high-resolution filtering method of gravity-magnetic anomalous apparent-velocity for implementing apparent velocities filtering processing of Bouguer gravitational anomaly in Dongying depression,the horizontal slices from the shallow to the deep are acquired.It is discovered that the shallow (1～5km) anomaly mainly reflects the Es-Ed shallow structures ;the deep (6～10km)anomaly mainly reflects the Es-Ek structures.11 larger faults are preliminarily determined,among which there are 2 faults that have significant influence on the whole areas,i.e.110km long and NNW orientated Hui-Dong big fault and NNW-oriented Chen-Dong subtle fault.Meanwhile.10 hidden low-amplitude rises are interpreted,which provided a foundation for knowing the deep structures in the areas and pointed out the targets of following oil/ gas exploration.
