Аннотация

The work is devoted to the development of a comprehensive lithological and electrophysical interpretation of electromagnetic sounding data to determine the material composition, distinguish lithological types and study electrophysical parameters of the Bazhenovskaya Formation rocks and its stratigraphic analogues in the central regions of West Siberia. According to high-frequency electromagnetic log soundings, the frequency dependences of the specific conductivity and relative dielectric permeability of the Bazhenovskaya Formation rocks are established. Using them, complex lithological-electrophysical models have been first constructed, and the basic laws of the influence of rock-forming components (clay, carbonate, siliceous material, organic matter and pyrite) on the dispersion properties of bazhenites have been studied. Based on the proposed new approach to assessing the content of rock-forming components according to electromagnetic soundings, the main lithological types of the Bazhenovskaya Formation rocks are identified as on the modern classification. Lithological and electrophysical models of the Bazhenovskaya Formation deposits are constructed invoking significant amounts of empirical data.
