This work presents the results of modelling the elastic wave propagation in a cluster of parallel fractures for two cases: the cluster of the fractures, parallel to the boundaries of the modeling grid, and a cluster of the inclined fractures. It is relatively easy to solve the modeling problem for the first case, when the fractures are vertical or horizontal, and therefore parallel to the boundaries of the grid. The second case, including the inclined fractures, is more difficult for modelling and computing. In this paper, we discuss a new approach and present the results of modelling the wave propagation in a cluster of parallel two-shore extremely thin fractures. The wave reflections for both cases are analyzed. The modeling results show that the amplitudes of the elastic field for the fractures, parallel to the boundaries of the grid, and for the inclined fractures show the cross correlation. The developed method can be used in interpretation of seismic data in the areas with complex fractured geological structures typical for HC reservoirs.
