地震地电学前兆深井立体综合观测技术思路

摘要

The technical thought on the comprehensive measurement of the seismological geo -electric precursor ob-served in a deep borehole are put forward.A suitable place is chosen.A deep borehole is drilled.Different meas-uring devices with different directions and depths are installed.Traditional measurements on the ground are re-placed with that in a deep borehole.With the borehole measurements,many kinds of interferences are avoided or reduced effectively.%提出了地震地电学前兆深井立体综合观测的技术思路。设计合适的观测井深度，根据观测井布局，采用深井钻探技术打好钻孔，在不同方向的位置上，按不同深度放置不同项目的测量装置（观测探头），改传统的地表平面观测为深部垂向及水平方向观测，并实现地震前兆立体综合观测。深井观测方法可有效避免地表观测的干扰影响，取得更好的观测效果，提高地震监测预报水平。
