一、概述数字地电仪主要是用于测量地下岩层的视电阻率,同时也适用测量大地自然电位。而其主要目的是测量视电阻率,通过对地下岩层的连续测量,观测视电阻率的相对变化量,以寻求与地震信息有内在联系的前兆现象,为地震预报与地震研究工作提供资料。该仪器主要由双积分式模数转换器,程序控制器和数字记录器等三个部分所组成。由于测量岩层视电阻率(特别是深部)方法本身的特点,通常测量仪表输入端将引入上千米
I. Overview Digital geoelectric instrument is mainly used to measure the apparent resistivity of underground formations, but also for measuring the natural potential of the earth. Its main purpose is to measure the apparent resistivity. Through the continuous measurement of underground strata, the relative change of apparent resistivity is observed to seek the precursory phenomena that are intrinsically linked with the seismic information and provide information for earthquake prediction and seismic research. The instrument is mainly composed of three parts: dual integral ADC, program controller and digital recorder. Due to the nature of the method of measuring apparent resistivity (especially deep) of the formation, it is typical that the meter input will introduce a kilometer
