摘要
检波器是石油物探地震数据采集系统中最前端的设备,是将地面振动信号转变为电信号的一种机电转换装置,其质量的好坏将直接影响地震记录的质量。简要介绍了建立地震检波器测试仪检定标准装置的重要性,详细论述了其测量不确定度的评定方法,并对测量不确度进行了验证。
A geophone is one of the most front-end equipment for seismic data acquisition in geophysical exploration,which is a switching unit for turning the surface vibration signals into electric signals,its quality will influence directly the quality of seismogram,the importance of establishment of a standard inspection device for the seismic geophone detector.The method for evaluating the uncertainty of the detector is discussed in detail and the uncertainty detection is proven.
