Starting from theoretic analysis, the paper discussed intrinsic character and pattern character of geophone and indicated that the cascade geophone pattern is benefit to enhance the amplitude of signal. The results of field test showed that adopting cascade geophone pattern can be results of good continuation of phase, enhanced amplitude and high signal-to-noise ratio on the records. Therefore, adopting cascade geophone pattern improved seismic data quality without increasing operation costs.
