The processing technology of narrow azimuth Quasi three-dimensional seismic data acquisition by single source and single long streamer system in marine seismic exploration
The structure of Mesozoic in Chaoshan sag in the north of the South China Sea is quite complex,so two-dimensional seismic data imaging can not accurately reveal the inside of the structure,and the environment in this area is complex and not suitable for conventional multi-cable three-dimensional seismic data acquisition system.Based on the characteristics of quasi three dimensional seismic data acquisition by single source and single long streamer system,the authors used air-gun de-bubble technology in combination with multiple suppression method,Compact Fourier Interpolation technology and three-dimensional prestack time migration technology in the seismic data processing project.It is for the first time that three-dimensional prestack time migration data were obtained in this area,and the quality of the imaging profile is greatly improved relative to that of the two-dimensional data.It can accurately reveal the inner curtain of the thrust structure and solve the problem that can not be solved by the former two-dimensional seismic exploration.
