宁德地震台地下流体单井综合观测系统故障分析

宁德地震台1号井地下流体单井观测系统为多手段观测,在长期的观测运行过程中,由于仪器设备等自身的条件、工作人员的维护不到位和仪器长期不间断使用均有可能导致设备工作不稳定出现故障,造成数据不稳定、失真和不连续等现象发生。目前,宁德地震台水位、水温和气氡三个测项均出现过故障,工作人员已对其进行排查解决,现结合数据的变化形态及仪器运行特点对这些故障现象进行总结、分析和讨论。

Single well observation system for underground fluid of No. 1 well in Ningde seismic station, provides many ways of observation. During the long-term observation operation, Due to the conditions of equipment, such as equipment, staff maintenance, and long-term uninterrupted use of equipment, it is possible to cause equipment instability and failure, resulting in instability, distortion, and discontinuity of data. At present, the three measuring items of water level and water temperature and radon of ningde seismic station have all been malfunctioned, and the staff has checked and solved them. Now, these fault phenomena are summarized, analyzed and discussed in combination with the changing patterns of data and the characteristics of instrument operation.
