电法勘探正向高分辨率的三维方向发展,以便解决能源、矿产资源勘查问题,并且还能解决水工环等地质问题。要实现三维电阻率测量,得到地下介质更精细的三维电性结构特征,需要解决如何采集高分辨率的三维电阻率观测数据以及相应三维成像技术问题。本文正是基于此思想,依托科技部相关项目资助于2010年成功研制出了LQC-Ⅱ型三维电阻率测量系统。本文通过重点阐述三维观测方式以及应用效果等内容,通过野外实验等各项测试表明LQC-Ⅱ型三维电阻率测量系统性能基本稳定,测量结果可靠。
Electrical prospecting is developing in the direction of high-resolution three-dimensional, in order to solve the energy, mineral resources exploration issues, but also to solve the hydraulic ring and other geological issues. To achieve the three-dimensional resistivity measurement and obtain the finer three-dimensional electrical structural characteristics of underground media, it is necessary to solve the problem of how to acquire high-resolution three-dimensional resistivity observation data and the corresponding three-dimensional imaging technology. This article is based on this idea, relying on science and technology projects funded in 2010 successfully developed a LQC-Ⅱ three-dimensional resistivity measurement system. This article focuses on three-dimensional observation methods and application effects and other tests through field experiments and other tests showed that LQC-Ⅱ three-dimensional resistivity measurement system performance is basically stable, the measurement results are reliable.
