云南省罗茨地电场的干扰排查及数据变化特征分析

Analysis of interference investigation and data change characteristics of the Luoci geoelectric observatory station in Yunnan Province

  • 摘要: 本文以罗茨地电场观测资料为研究对象,利用该地电场观测数据对其主要干扰源进行定位及分析,发现其主要干扰源为电极引线破损、测区温泉经营户抽水机漏电、大型基建施工及降雨所致,分别介绍此四类主要干扰源的排查过程及其典型变化形态,为干扰问题提出一些解决思路;利用相关性分析、差分等手段对该地电场观测质量进行评价,并归纳总结在实际工作中提升观测质量的方法;在同一个地电暴事件中,通过与周边的元谋苴林地电场做观测数据的对比,总结罗茨地电场数据在地电暴事件中的变化特点并分析两个地电场观测记录不同的原因。该论文为台站工作人员对该地电场观测资料的认识和把握提供较好的参考意义,并为噪声识别和震情分析提供参考价值,以及后期该地电场的改造提供科学依据。

     

    Abstract: In this paper, the observation data of the Luoci geoelectric observatory station are taken as the research object, and the main interference sources are located and analyzed by using the observation data of the geoelectric observatory station. It is found that the main interference sources are the damage of the electrode lead, the leakage of the water pump of the hot spring operators in the survey area, the large-scale infrastructure construction and the rainfall. The investigation process and typical changes of these four main interference sources are introduced respectively, and some solutions are put forward for the interference problem. The quality of the geoelectric observatory station observation is evaluated by means of correlation analysis and difference, and the methods to improve the observation quality in practical work are summarized. In the same geoelectric storm event, by comparing the observation data with the surrounding the Yuanmoujulin geoelectric observatory station, the variation characteristics of the Luoci geoelectric observatory station data in the geoelectric storm event are summarized and the reasons for the difference between the two geoelectric observatory station observation records are analyzed. This paper provides a good reference for the station staff to understand and grasp the geoelectric observatory station observation data, and provides a reference value for noise identification and seismic analysis, and provides a scientific basis for the later transformation of the geoelectric observatory station.
