The underground structure in the SN Area is fragmented,with developed faults.At the same time,it is interfered with and affected by large-scale and multi-stage intrusion of diabase layers,resulting in poor quality of most seismic data in the area,unclear fault breaks,unrealistic formation attitudes,and great difficulty in structural interpretation.Omnidirectional angle domain migration imaging not only includes seismic and geological information from different underground directions but also carries out geological structure-based subsurface dominant dip angle stacking imaging based on the response of faults in different orientations and dip angles,combined with geological sedimentary characteristics,to better identify faults in complex structural areas and improve the degree of trap implementation.
