将安徽六安2015年安装的2台GL-S60B井下地震计记录数据，分别与在各自井口架设的BBVS-60地表地震计记录数据进行对比，得到了噪声有效值、频谱特征和有效动态范围等，初步获得了井下地震计在六安的运行情况。研究表明，井下地震计观测效果明显优于地面地震计，这对于未来地震台站选址、仪器选型等具有参考意义。
This paper compares seismic records of two GL-S60B downhole seismometers installed in Lu'an, Anhui in 2015 with those recorded by two BBVS-60 surface seismometers installed at the respective wellheads. The effective values of noise, spectral characteristics, and effective dynamic range were obtained. The operation status of downhole seismometers in Lu'an was also initially obtained. The study shows that the observation effectiveness of downhole seismometers is significantly better than that of surface seismometers, which has reference significance for seismic station site determination and instrument selection.
