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 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
