Comparing with the analog geophone, the digital geophone is characterized by wide frequency-band, wide dynamic range and high sensitivity, but the environmental noise is rather higher due to the receiving by the single geophone for the individual trace. The analyses and contrast of the signal-to-noise ratio and frequency charac- teristics for the data received by above two geophones in West Slope of Daqing Oilfield show that the ratio value of a certain frequency can be obtained by the normalized spectrum; the signals of different frequency bands can be thoroughly and effectively imaged by the parallel processing with the help of different noise suppression methods and deconvolution parameters ; the imaged effects of the seismograms received by the digital geophones can be fully and availably applied in the exploration arrangement of West Slope of Songliao Basin.
