超高密度电法是建立在常规高密度电法基础上的一种地球物理探测方法,其继承了高密度电法诸多优势,并且通过多通道数据采集,进一步优化采集方式,提高电极利用率、缩短实际操作时间、增大数据采集量,从而提高工作效率和准确性。本文首先简单介绍了超高密度电法以及改进型超高密度电法的基本原理、观测方式、正演模拟和反演成像的理论基础以及发展;其次针对一个典型的模型,分别通过对比超高密度电法和改进型超高密度电法与常规高密度电法对此模型的响应,对比分析之后确认改进型超高密度电法比常规高密度电法拥有更佳的探测效果,并且提高工作效率。
Ultra-high density electrical method is based on the conventional high-density electrical method based on a geophysical detection method, which inherited the advantages of high-density electrical method, and through multi-channel data acquisition, to further optimize the acquisition method to improve electrode utilization, Shorten the actual operation time, increase the amount of data collection, thereby enhancing work efficiency and accuracy. In this paper, the basic principles, observation methods, the theoretical foundation and development of forward modeling and inversion imaging are briefly introduced in this paper. Secondly, for a typical model, by contrasting ultra-high density Density electric method, improved ultra-high density electric method and conventional high-density electric method to this model. After comparative analysis, it is confirmed that the modified ultra-high density electric method has a better detection effect than the conventional high-density electric method and improves the work effectiveness.
