Wide
azimuth seismic is a kind of 3D seismic data acquisition-processing technique
with the ratio between transverse and longitudinal receiver unit larger than
0.5.Wide azimuth seismic is characterized by whole distribution of azimuth
angle and even distribution of offset. In this paper, the authors introduced the wide azimuth
seismic acquisition and processing examples in Luo42 area and Shang741 area of
Jiyang Depression, and Zhuang1 well area in central Junggar Basin. Moreover, wide
azimuth seismic data was applied for predicting shale fractured reservoir and
igneous rock fracture development belt, as well as characterizing the sand
bodies in Zhuang1 well area. The results indicate that wide azimuth seismic is
effective for the geologic bodies with anisotropy and strong heterogeneity, but
there is no advantage for identifying sand bodies and inversing physical
properties by using wide azimuth seismic data.
