Research on vertical cable seismic interferometry imaging

Vertical cable seismic (VCS) is a reflection seismic exploration technique, which is mainly used for structural imaging in high dip angle areas. Because the source and receiver points are usually not in the same plane, it is not possible to use conventional velocity analysis to obtain the velocity field. In most cases, the velocity field of the streamer data is processed in the same survey area as the VCS. Seismic interferometry is to obtain new seismic signals by cross-correlation or convolution operation of seismic signals received by different receivers. Therefore, we propose to apply seismic interferometry to VCS exploration. Compared with conventional VCS data processing, this method does not need towed streamer data and improves exploration efficiency. In this paper, the method is applied to model data and actual data of South China Sea respectively to obtain the stacking profile. The results show that this method is applied to VCS data, and the stacking profile is continuous in phase axis and clear in structure.
