论检波器组合的连接方式

Circuits connection of geophone array

在石油、地震勘探中,为了压制干扰,每道地震信号都采用多个检波器的组合。分析了检波器组合的等效电路,推导出检波器组合的传输特性——检波器组合输出电压与检波点地面振动速度的数学关系,依据这一理论,可以确定,采用串联数等于并联数的串并联方式是检波器组合最佳的电路连接方式。

In seismic prospecting for oil each seismic channel uses multi-geophone array for noise suppression. The equivalent circuit of geophone array is analysed. The transfer characteristic of geophone array which mathematic relation of output voltage of geophone array and ground motion velocity is derived. On the basis of this theory it can be determined that a geophone array consisting of the same number of geophones in series as number of strings in parallel is optimum.
