摘　　要：在陆上地震资料采集中,遇到大面积的水库、泻湖、堰塘等水域地段时,采用陆上常规检波器已无法保证其接收效果,甚至无法埋置而导致大量的丢道现象发生。这里围绕水下压电检波器在宽水域水库、窄水域水沟中接收效果分析,并与陆上常规检波器20DX-10的接收效果进行对比,来探讨采用水下压电检波器在陆上地震资料采集中的适用范围和效果,为今后陆上地震资料采集在水域分布面积较广区域使用水下压电检波器接收提供一定的参考。As water body such as reservoir,lagoon,pool,pond,river are often encountered in land seismic survey.In this case,the quality of the data is often bad because using different type of receiver or discarding the traces.This paper compared the performance of piezoelectric hydrophone and geophone through experiments,and then constructive advice was given about the using of hydrophone in the water body on land seismic acquisition so as to get better data.
