Аннотация

Key macroscopic characteristics of hydrocarbon-bearing formations (necessary information for development of the oil and gas deposits) are determined mainly by microscopic structural features of the reservoir pore space. Combination of effective medium theory with high-quality laboratory experiments on thermal and acoustic properties of rocks provides important information for petrophysics and prospecting geophysics. An example is demonstrated with well-known rock-Bentheimer sandstone - which is widely used for many purposes. 20 cores were accurately studied at the normal conditions at air-and watersaturated states. Parameters of rock microstructure were estimated, the forward EMT-based model of rock properties has been created using two different methods, and the elasticity tensor of Bentheimer sandstone was reconstructed. The constructed model was successfully validated by comparison the calculated thermal conductivity, compressional and shears wave velocities with corresponding laboratory measurements at different saturation state. Demonstrated that preliminary validation of EMT-based model on extended experimental dataset is critically important, that can have an impact on successful solution of different problems of prospecting geophysics. Consistent model promotes deeper understanding the link between different rock properties, results can be used for improvement different engineering models of effective properties.
