Abstract
The study is aimed at analyzing the applicability of the logging tool with toroidal coils in the sections of deviated oil-and-gas wells. We carried out a three-dimensional finite-difference simulation of the electromagnetic signals in geoelectric models of oil-, gas-, oil-water- and water-saturated reservoirs for the entire set of operating modes, frequencies and positions of the receiver toroidal coils. Characteristic features of the signals were revealed depending on the resistivity contrast and reservoir thickness at various well deviation angles.
