Abstract：Wide-azimuth seismic data sets are rich in azimuth-angle and offset information,which is very helpful after processing in the offset vector tile (OVT) domain for the characterization of subtle faults and low-relief structures.With interpretation-oriented processing tools provided by GeoEast System,fault-sensitive seismic attributes such curvature are extracted from azimuthal seismic data.Subtle faults and shale reservoir fracture characte-ristics of Wufeng-Malong member in the Block ZJB are accurately identified,which provides a good basis for the future horizontal well trajectory design.
