Abstract

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.

Key words： long streamer single source and single cable quasi three dimensional 3-D perstack time migration marine geologic survey seismic data
