电阻率剖面法数据反演包括根据野外测量到的视电阻率值来估计电阻率的空间分布和岩层的厚度,其中的视电阻率是电极间距的函数。解决这种反演问题的常规典线拟合技术存在着某些缺陷,它可通过迭代线性技术加以克服,然而,即使假设源体的形状已知,它也需要好的初始模型才行。尽管近几年来反演技术取得了进展,但仍没有可靠的岩脉和球状简单模型电阻率剖面法数据的反演方法,而这二
Resistivity profile data inversion consists of estimating the spatial distribution of resistivity and the thickness of the formation based on the apparent resistivity values measured in the field, where apparent resistivity is a function of electrode spacing. The conventional classical line fitting technique to solve this inversion problem has some drawbacks that can be overcome by iterative linear techniques, however, it requires a good initial model even assuming the shape of the source body is known. In spite of the progress made in inversion technology in recent years, there is no reliable inversion method for resistivity profile data of simple models of dikes and spheres
