The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretical model will be verified using numerical simulations and ultrasonic measurements made on synthetic porous and fractured samples. The results are expected to benefit seismic exploration and the production of oil and gas in fractured reservoirs.

该项目的目的是建立一个裂缝性多孔储层岩石弹性特性的理论模型，同时考虑到孔隙和裂缝之间的波致流体流动。这将通过基于裂缝作为多孔岩石中的不连续面的模型和各向异性多孔介质中的波传播理论的理论分析来完成。理论模型将使用数值模拟和超声波测量合成多孔和裂缝样品进行验证。研究结果对裂缝性油气藏的地震勘探和开发具有一定的指导意义。
