Abstract：Hardware equipmentofseismic exploration has been gradually developed in recent years,the numbers of acquiredseismic trace are expanded from original severalhundredsto severalthousands,even ten thousands,which makes land wide-azimuth 3-D seismic exploration possible. Through cases study of wide-azimuth aequisition,processingand interpretation in the west of China and after comparison of differences in amplitude imaging,coherent data volume and phase for wide-narrow-az-imuth 3-D seismic exploration,the paper considered that the wide-azimuth seismic exploration has widespread application prospect in lithologic and directional fracture exploration.
