Two-dimensional numerical inversion is widely used by leading foreign oilfield services companies to process electrical measurements from intervals of deposits with complex structure. However, the design features of the instruments greatly complicate the use of this approach for processing measurements of Russian electric logging methods. For this reason, now two-dimensional inversion of Russian electric logging measurements is limited to processing small data intervals in scientific researches. We have developed software and technique for a two-dimensional data inversion of high-frequency induction logging sounding (VIKIZ) and Russian lateral logging (BKZ), measured in intervals of thin anisotropic layers interbedding. With use of high-precision numerical two-dimensional simulation, it becomes possible to more accurately estimate the electrophysical parameters of the environment compared with the traditional one-dimensional approach. Software and technique have been tested on a large volume of realistic isotropic and anisotropic models of terrigenous sediments with a complex invasion profile and on the practical data of BKZ and VIKIZ, measured at intervals of Western Siberia terrigenous sediments. The results of testing confirm the applicability of new software for building geoelectric models of complex sediments with evaluation of their vertical resistivity and dielectric permittivity.
