Study on The Influence Law of Side Effect of Two-dimensional ERT

Abstract

As a traditional exploration method, two-dimensional high density resistivity method has been widely used in various projects. However, when using this method for exploration, three-dimensional geological bodies often affect the two-dimensional detection results, which is the side effect of two-dimensional high density resistivity method. Although the three-dimensional high density resistivity method can effectively remove the side effect of the two-dimensional high density resistivity method, the application of the three-dimensional high density resistivity method is often limited by the performance and cost of the instrument. Therefore, it is of great significance to explore the influence law of the side effect of the two-dimensional high density resistivity method. In this paper, through the method of numerical simulation, by comparing the data of different inversion arrays, the influence of abnormal body size, type, different arrays and other factors on the side effect is discussed.
