超高密度电法是建立在常规高密度电阻率法基础上的一种新型地球物理探测方法,其继承了高密度电法的诸多优势。首先在数据采集过程中使用多通道数据采集方式,充分利用已经布好的电极,除供电电极以外其他电极均可以进行数据采集,在此过程中缩短了因为进行单一数据采集而消耗的时间,并且增大了数据采集量,从而提高了工作效率;其次,改进型的超高密度电法可以进行多种装置采集所得到的数据联合反演,避免单一数据反演产生的结果畸变,从而提高了探测精度。本文首先介绍了此方法的基本原理、观测方式等;其次通过一个典型模型进行超高密度电法和常规高密度电法的对比分析,确认此方法在实验过程中明显提高了工作效率;此后,在进一步的分析过程中,使用改进型超高密度电法,将若干种装置采集得到的数据分别进行联合反演,还进行了多参数联合反演,取得了良好的应用效果。
Ultra-high-density electrical method is based on the conventional high-density resistivity method based on a new geophysical exploration method, which inherited the advantages of high-density electrical method. First of all, the multi-channel data acquisition method is used in the data acquisition process to make full use of the already-arranged electrodes, and the other electrodes except for the power supply electrodes can collect data. In this process, the time consumed for single data acquisition is shortened, and Increase the amount of data collected, thereby increasing the work efficiency; Secondly, the improved ultra-high density electrical method can be a variety of devices collected data from the joint inversion to avoid single data inversion results distortion, thereby increasing Detection accuracy. This paper first introduces the basic principles of this method, observation methods, etc .; secondly, through a typical model of ultra-high density electric method and conventional high-density electric method comparative analysis confirmed that this method significantly improves the work efficiency during the experiment; thereafter, In the further analysis process, using the improved ultra-high density electrical method, the data collected by several devices were separately combined inversion, but also conducted a multi-parameter joint inversion, and achieved good results.
