Research on vertical cable seismic multiples imaging processing
Vertical cable seismic (VCS) is a kind of reflection seismic exploration technique. Multi-node hydrophone array set perpendicular to the seabed and records wave field inspired by air gun. Vertical cable seismic exploration can make up for the disadvantages of the harsh conditions of towed cable seismic exploration. VCS technique is also convenient to be used in monitoring the underground geologic changes in the stage of gas hydrates development. In this paper, VCS data collected near the gas hydrates test and mining area of the South China Sea was processed and obtained multi-wave imaging profiles. It is shown that the VCS data has such advantages as high signal-to-noise ratio, high fidelity, and so on compared to the towed cable data, especially in the imaging of underground steep dip angle geological structures.
