地震勘探用压电加速度检波器频响特性分析
|
摘要
为了将压电式加速度传感器应用于地震勘探,从理论上分析了接地刚度以及尾座(锥)附加质量对检波器接收性能的影响,通过室内模拟实验和现场测试实验进行了幅频和相频响应特性分析,得到了压电式加速度检波器具有宽频响应的特性。实验结果与理论分析结论相互印证,此结果能满足高分辨率地震勘探对检波器的要求。
According to the using of tailcone and tailstock designed for piezoelectricity acceleration seismometers,the paper analysed the receiving properties of geophone influenced by the grounding stiffness and the added mass caused by tailstock,the amplitude-frequency and phase-frequency characteristics through the indoor simulation experiment and field tests.The theoretical analysis is consistent with the experimental results which proves the wideband characteristics of the piezoelectricity acceleration seismometer.and meets the requirement of high-resolution seismic exploration asked for the geophone.
