Abstract: In the field of seismic exploration, seismic prospecting using longitudinal (P-w), shear wave (S-w) and transverse wave (PS-w) combined exploration has become a hotspot in recent years. In this paper, the overland three component shear wave exploration method is introduced into the natural-gas-hydrate exploration. It firstly describes the mature technology and advantages of the shear wave method in land seismic exploration. Combined with the natural-gas-hydrate geophysical and metallogenic characteristics in the South China Sea, it gives the possibility of suitable technological application, and puts forward a series of technical schemes. This paper also introduces the research progress and problem of the three component ocean wave exploration for natural-gas-hydrate conducted by the Guangzhou Marine Geological Survey since 2000, and raises some ideas and suggestions.
