Abstract

Abstract:

Ray tracing method of basing on the subsurface geology model is very important for defining some parameters during marine seismic exploration. The signal reflected from underground interface can be directly viewed when different emission locations are chosen. Thus the effect of different seismic survey geometry on seismic data acquisition can be under-stood. It is also very significant for using multi-waves both to reveal the internal velocity structure of gas hydrates ores and enhance the resolution of gas hydrates bearing formations. By analyzing the application of ocean bottom seismometers (OBS) on the gas hydrate exploration abroad, the method of ray tracing was introduced on the layout design of OBS in this paper; PS wave was recorded in the sea test, which gives satisfied application result.

Key words: ray tracing method, natural gas hydrate, ocean bottom seismometer, layout design
