铀矿资源勘查三维电阻率采集系统与应用研究

3-D Resistivity Data Acquisition System and Application Study in Uranium Exploration

LQC-Ⅱ三维电阻率采集系统采用多子站、分布式智能电极设计思路,实现了多通道同时快速并行采集,通过16个子站排列组合实现了大深度的勘查要求。文章对LQC-Ⅱ型三维电阻率测量系统的基本原理、工作方法和技术作了概括性论述。利用该仪器进行了野外试验研究,对采集数据进行了三维反演,得到的水平方向和垂直方向电阻率切片均与钻孔资料吻合。

The design idea of multi - sub - station and distributed intelligent electrode is adopted in the LQC - II - type 3D resistivity data acquisition system, which results in a multi - channel fast parallel acquisition. The combination of 16 sub - stations can reach large exploration depth. The basic principle, working method and technology of the system generally were discussed in this paper. Field experiment and three - dimensional inversion of measured data with the instrument were carried out, the interpreted results of horizontal direction and vertical slice inosculated well with borehole data.
