电法勘探中并行数据采集与传统数据采集效率的比较研究

A camparative study of Efficiency about traditional electrical and collateral electrical data collection in electrical prospecting

在电法数据的采集方面:传统的电法勘探数据采集量少、时间长,从而效率较低,通过研究地震勘探中并行数据采集的优点,使电法勘探数据采集模拟地震勘探的数据采集方式.并行电法数据采集采用两种主要的采集方法:一种是单极供电(称为AM法)、另一种是双极供电(称为ABM法).本文主要通过对数据量的分析比较得出:在同样电极组合条件下,并行采集物理点的数据是随着电极数量的增加而成二次抛物线增长,从而使电法勘探数据采集效率得到空前提高.

Some crucial disadvantages exist in the traditional high density resistivity method.For example the needed data would cost a very long time.So the advantages of seismic survey such as parallel and multiple data collection are well considered.The idea of developing collateral electrical data collecting most benefits from seismic survey.We develop two ways to collect data：one is monopole sending power（called AM method）,the other is dipole sending power（called ABM method）.In either way,the electric meter can make all electrodes work at the same time,so efficiency is improved sharply.
