Resumo: | |||||||||||||
The Nonlinear Hydraulic Diffusivity Equation (NHDE) models the singlephase flow of fluids in porous media considering the variation in the properties
of the rock and the fluid present inside its pores. Normally, the dimensionless linear solution for the flow of oil is performed using the Laplace and
Fourier transform or Boltzmann transformation and provides the unsteady
pressure profile in Cartesian coordinates given by complementary error function erfc(xD, yD, tD) and in cylindrical coordinates described by the exponential integral function Ei(rD, tD).
This work develops a new analytical model based on an integro-differential
solution to predict the formation mechanical damage caused by the permeability loss during the well-reservoir life-cycle for several oil flow problems.
The appropriate Green s function (GF) to solve NHDE for each well-reservoir
setting approached in this thesis is used. The general solution is implemented
in the Matlab (trademark) and the mathematical model calibration will be carried out
by comparing the solution obtained in this work to the porous media finite
difference oil flow simulator named IMEX (trademark). The general solution of the NHDE
is computed by the sum of the linear solution (constant permeability) and the
first order term of the asymptotic series expansion, composed of the nonlinear
effect of the permeability loss. The instantaneous permeability loss effect is
clearly noticed in the diagnostic and specialized plots.
