地震地电场前兆观测方法创新与应用——河南范县豫01井钢管电极垂向地电场观测资料异常与地震的关系

Innovation and Application of Earthquake Precursor Observation Method in Seismic Geoelectric Fields——The Relationship Between Anomaly of Vertical Geoelectric Field Observation Data of Steel Tube Electrode and Earthquake in Well "Yu 01" in Fan County, Hen

为了更好的获取地震前兆异常信息,依据深井电极垂向地电场观测方法技术思路,开发了深井钢管作电极开展垂向地电场观测的方法。该方法充分利用现有地震台站已有条件,将深井钢管作电极开展地电场观测,开辟了地震前兆观测新途径,效果良好。在河南省范县豫01井地震台利用豫01井井管作电极,开展了深井钢管电极垂向地电场观测实验。豫01井垂向地电场观测资料异常变化与观测井周围100km范围内地震活动具有较好的对应关系。

In order to more effectively obtain earthquake precursor abnormal information, according to the technical idea of vertical geoelectric field observation method with deep well electrode, the method of using deep well steel tube as electrode to carry out vertical geoelectric field observation is developed. This method makes full use of the existing conditions of the old station, and uses the deep well steel tube as the electrode to carry out the geoelectric field observation, which opens up a new way of earthquake precursor observation with good effect. The vertical geoelectric field observation experiment with steel tube electrodes in deep well was carried out at well Yu 01 seismic station in Fanxian County, Henan Province. There is a good correspondence between the anomaly of vertical geoelectric field observation data of steel tube electrode and earthquake in Well "Yu 01" in Fan County, Henan Province.
