摘要
OhmMapper是用于去测量高阻区地下电阻率的一种电容耦合电阻率系统。R)是一种新颖的物探方法,它是利用电容向下供电,并利用电容来测量地表耦合电位,由于不需要接地,电容耦合电阻率法解决了常规电阻率法在表层电阻率高的地区难以布极、供电困难等问题。OhmMapper具有信息丰富(可以连续采集)、效率高(沿地面拖动测量)的特点,是一种在浅层勘探中很有效的仪器。本文将对这一种方法的原理、工作方法技术及仪器的操作方法进行介绍的基础上,对实验采得的数据进行处理分析,对OhmMapper仪器的使用效果做一定的评价。

ABSTRACT
The OhmMapper is a capacitively-coupled resistivity system designed to measure subsurface resistivity in areas with high subsurface resistivity. Capacitivity -Coupled Resistivity (CCR) Method is a new method of geophysical exploration, which uses capacitor to supply current to underground and measures coupled electric potential as well. Because of without grounding, the Capacitivity -Coupled Resistivity method solved such problems that it is difficult to arrange electrode and supply current in the area where the resistivity is very high in near –surface in ordinary resistivity method . The OhmMapper which is a effective instrument in shallow exploration, has such advantages as abundant information (continuous acquisition) and high efficiency ( dragging survey along the ground). On the basis of introducing the principle and working ways of the method and the operation of instrument OhmMapper , the paper also describes the dealing with the data which acquired and analyzing it in order to evaluate the effective of the instrument OhmMapper .
