Compression Pulse Propagation in Fractured Porous Medium

The process of propagation of compression pulses in a fractured porous medium has been studied. The study was carried out within the framework of a three-velocity, three-stress mathematical model. The problems are considered in one-dimensional and two-dimensional formulations. The computer implementation of the model is carried out using the methodology previously developed by the authors. The features of this wave process are revealed. With a low intensity of mass transfer between the systems of pores and fractures, there is a mismatch of pressures in the pores and fractures during wave propagation, and with an increase in intensity, a rapid pressure equalization occurs. Comparison of solutions in one-dimensional and two-dimensional cases showed that their difference is due to the geometry of the process.
