摘　　要：依据深井(井下)电极垂向地电场观测技术思路,本文提出了利用深井钢管做电极开展垂向地电场观测的新方法,开辟了地震地电场前兆观测的新途径。地震台可利用深井摆测震井、地下流体观测井等现有的深井钢管条件,增加地电场地震前兆观测项目,同时不需要太大的投资。在台站具备深井条件时,该方法易于推广和应用,效果良好。According to the technical idea of deep well(downhole)electrode vertical geoelectric field observation,this paper proposed a new method of using deep well steel pipe as electrode to carry out vertical geoelectric field ob⁃servation,which opened up a new way of seismic geoelectric field observation.Seismic stations can use existing deep well steel pipe conditions such as deep pendulum seismic logging wells and underground fluid observation wells to in⁃crease geoelectric field seismic precursor observation projects without requiring too much investment.When the sta⁃tion has deep well conditions,this method is easy to popularize and apply,and the effect is good.
