检波器接收能力与地震波的完整性、精确性分析

Analysis of integrity and accuracy for geophone receiving capability

地震信号的完整性和精确性对地震资料的应用影响很大,基于对10 Hz电磁感应式动圈检波器和加速度检波器进行试验分析,从结果显示,加速度检波器的加速度信号在信噪比高、精度高、分辨率高、信息量大等方面具有较好的优势,能够更好地满足当前和未来地震勘探的要求.

The integrity and accuracy of seismic signals have a great influence on seismic data.Based on the research of two geophone types(10 Hz moving-coil velocity and piezoelectric acceleration),test results show that the acceleration signal can content the requirements of high signal to noise ratio,high precision,high resolution and large amount of information for seismic signal in current and future.
