Abstract:The analysis of vibration characteristic of geophones shows that different geophone array circuits creat different impedances (Z) of external circuit,causing the corresponding variations of sensitivity,damping coefficient and frequency of geophone.The three parameters of geophone are important factors controlling data acquisition quality.The sensitivity of specific PE-3 geophone array is estimated. The response curves of three different kinds of geophones and of PE-3 geophone in different array patterns are given respectively in the paper.The points for attention in using PE-3 geophones are listed detailedly,The importance of the determination of serial or parallel geophone array patterns in field operation is outlined so as to help the explorer to design optimum geophone array.
