| 摘 要： | 宁夏回族自治区数字化测震台网由14个数字化测震台站构成,其中宁夏灵武和宁夏陶乐为井下式数字化测震台站。宁夏陶乐数字化观测井此前使用JDF-2型号地震计,但由于仪器老化导致记录波形失真,经研究决定,于2018年12月底将宁夏陶乐观测井的地震计及数据采集器更换为井下短周期GL-S2B型号地震计、EDAS-24GN型号数采。在北京港震仪器设备有限公司技术人员的配合下,宁夏测震台网工作人员对更换后的井下短周期GL-S2B型号地震计、EDAS-24GN型号数据采集器进行了方位角校正、阶跃标定、正弦标定、台基噪声功率谱密度测试等参数测定,各项测定结果均符合井下地震计及数采的安装规范,且记录波形良好。

| Abstract: | The digital seismic network of Ningxia Hui Autonomous Region consists of 14 digital seismic stations,among which Ningxia Lingwu and Ningxia Taole are underground digital seismic stations.JDF-2 seismometer was used in Ningxia Taole digital observation well,but the recorded waveform was distorted due to the aging of the instrument.After research,it was decided to replace the seismometer and data collector of Ningxia taole logging with the downhole short period GL-S2B seismometer and EDAS-24GN seismometer by the end of December 2018.With the cooperation of the technicians of Beijing Gangzhen instrument and Equipment Co.,Ltd.,the staff of Ningxia seismological network measured the azimuth correction,step calibration,sine calibration,noise power spectral density test and other parameters of the replaced downhole short period GL-S2B seismometer and EDAS-24GN data collector,and all the measured results were in line with the installation of downhole seismometer and data mining Standard,and the recorded waveform is good. |
