摘要： 在地表地形复杂的地区进行低降速带探测时,采用常规地震小折射方法,在现场难以实施,而且效果往往不佳。为了解决这一问题,引进了瑞雷波法进行实验,取得较好成果。在地震测线上布置一定密度的瑞雷波探测点,结合少量的微测井资料,通过对瑞雷波资料和微测井资料的对比,推算出纵、横波比值。然后通过瑞雷波资料的处理、解释,计算出测区的静校正值,用于地震资料的处理。

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
