Abstract

The work is dedicated to theoretical basis of processing and interpretation of data of an electromagnetic logging tool with toroidal coils for studying rocks electrophysical macroanizotropy. The task being implemented is related to the development of algorithms and software for numerical simulation and data inversion. The behavior of signals in formations has been studied based on the results of mathematical modeling. The parameters of the tool are validated and its optimal configuration is revealed. Algorithms for transforming measured signals into apparent resistivity and coefficient of electrical macroanisotropy are developed. To quantify the parameters, a data inversion procedure in a complex environment model that corresponds to real geological conditions, has been created. The results of the studies allow to make a conclusion about the high spatial resolution of the developed electromagnetic logging tool and its applicability for revealing a thin-layered or fractured rock structure. The establishment of macro-anisotropic parameters makes it possible to improve the accuracy of the estimation of the reservoir effective thickness and fluid saturation.
