摘要
针对大部分沉积岩具有层理结构,从其电性上来看,它们是由各种不同电阻率的地层组成的,这样的地层其电阻率呈现出各向异性。在对电阻率断面进行观测时,要在层状介质背景剖面的基础上,利用二维电阻率扰动反演方法,将背景场环境中的电性层结构进行掌控,并对敏感矩阵进行计算,通过实验得到良好的效果。
For the majority of sedimentary rocks are bedding structure of electricity from its point of view, they are different types of resistivity of the composition of the strata, so that the resistivity of the formation and adoption of one of the direction of current, showing a anisotropic. Made use of two-dimensional layered media background resistivity inversion perturbation method, based on observations of the background cross-section of apparent resistivity profiles, to determine the context of electricity market structure, the use of resistivity perturbation method to calculate sensitivity matrix, through experiments get good results.
