为了定量地探讨激发极化法在水平地层上出现的激电负效应和超正(或峰值增强)效应,本文以三层断面为例,采用“临界电阻率法”和“稀释系数法”对其产生条件、作用范围、作用强度等内容及各种影响因素进行了较全面、系统的研究,给出了有意义的判断准则和若干有价值的规律。为了证明激电负效应的客观性和理论分析的正确性,文中还给出了有关模型实验结果。 In order to quantitatively investigate the negative effect of the induced polarization and the overcorrection (or peak enhancement) effect on the horizontal formation, this paper takes the three-layer cross section as an example and adopts the “critical resistivity method” and the “dilution factor method” Its production conditions, scope of action, intensity of action and other factors and a variety of influencing factors a more comprehensive and systematic study, gives a meaningful criterion and a number of valuable rules. In order to prove the objectivity of the negative effects of the shock and the correctness of the theoretical analysis, the experimental results of the model are given.
