| 摘 要： | 地震检波器的性能是高分辨率地震数据采集中的一个重要因素，对资料的品质影响很大。为此，作者在不同类型地区对目前在高分辨率地震勘探中常用的动圈式检波器、涡流检波器和数字检波器的性能进行了对比试验。通过野外工作的实际，总结了动圈式检波器、涡流检波器和数字检波器在不同表层地质条件地区的应用效果，提出了适合该类地区高分辨率地震检波器的性能指标，指出合理选择检波器类型和检波器的联接方式，能提高地震资料的信噪比和分辨率。

| Abstract: | The properties of the seismic geophones are important factors for high-resolution three kinds of geophones currently used in several regions with different geological features:desert, saline-alkali farmland, and carbonate areas in mountainous regions in order to test their property indexes. Based on the geophone vibration equation and from the property index effects of geophone and the connection of the geophones on seismic data, we analyzed seismic data quality acquired in the tested regions and suggest that suitable geophone property indexes, reasonable choice of geophone types, and the suitable geophone connection can enhance the signal/noise ratio of seismic data. |

| Keywords: | Property index geophone resolution natural frequency signal/noise ratio |
