Abstract: Using refraction method to detect low velocity layer in intricate area is difficult in field and poor in effect, generally. Rayleigh wave method is introduced to solve this problem. Some Rayleigh wave detecting points are integrated and compared with a few micro well logs on the seismic line, which can get the ratio of longitudinal wave and transverse wave. By processing and interpretation of Rayleigh wave data, static correction value in studied area can be calculated and used for seismic data processing. Study shows that good results can be gained by using this method.

Key words: Rayleigh wave method, seismic prospecting, low velocity layer, static correction, velocity
