Identification of Parameters of a Fractured-Porous Reservoir by the Data of Unsteady Fluid Inflow to Vertical Wells

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The author proposes a numerical algorithm to indentify filtration and capacitory parameters of a fractured-porous reservoir by the results of hydrodynamic investigations of the well on the basis of the Levenberg–Marquardt method, which belongs to the methods of minimization of second order. The algorithm makes it possible to determine the total set of such parameters of a fractured-porous reservoir as the permeability coefficients of fractures and blocks, the parameters of fluid crossflow between blocks and fractures, the characteristic delay times, the linear dimension of matrix blocks of rock, the piezoconductivity coefficients of blocks and fractures of the reservoir, the reservoir pressure, and the efficiency of the well.
