Abstract:
The properties of the seismic geophones are important factors for high-resolution seismic exploration and have a great influence on data quality. For this reason, we have tested 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 linkage characteristics 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 linkage characteristics can enhance the signal/noise ratio of seismic data.
