本文首先概述岩石在室内各种受载条件下电阻率的实验研究工作,这对于认识和理解电阻率变化特征、规律以及探索其机理起着重要的作用。但是在实验中主要采用4个固定电极的测量系统,它只能获得从某个深度到岩样表面的整个深度层的视电阻率变化的综合信息,而无法获得不同深度层的视电阻率变化特征,不利于进一步研究电阻率及其各向异性变化的机理。我们利用电阻率层析成像方法获得了多个方向的电阻率数据,据此可以获得随深度变化的电阻率及其各向异性曲线以及随应力变化的电阻率图像,可能为深入理解和研究电阻率变化机理起到积极的帮助。
This article first outlines the experimental research on the resistivity of rocks under various loading conditions in the interior, which plays an important role in understanding and understanding the characteristics and laws of the resistivity variation and exploring its mechanism. However, four fixed electrode measurement systems are mainly used in the experiment. It can only obtain the comprehensive information of the apparent resistivity change from a certain depth to the entire depth of the surface of the sample, but can not obtain the change of apparent resistivity at different depths Features, is not conducive to further study of resistivity and anisotropic changes in the mechanism. Using resistivity tomography, we obtained resistivity data in multiple directions, from which resistivity and anisotropy curves as a function of depth and resistivity images as a function of stress were obtained. It is possible to gain insight into and study the electrical resistance The rate of change mechanism played a positive help.
