Abstract
This paper addresses burning problems of Rock Physics modeling as applied to carbonate rocks. These problems include: a choice of Rock Physics method to relate the model’s parameters with experimentally measured elastic properties; construction of a model medium that reliably describes the rock microstructure at respective scale; a correspondence of Rock Physics model scale with the experimental scale. Special attention is paid to reservoir rocks of complex structure. For these rocks, incorrect description of isometric porosity distribution may lead to erroneous interpretation of change in velocities as effect of fractures. A separate section is devoted to Rock Physics modeling of fractured rocks at the seismic scale, which is based on results of geomechanical modeling.
