ABSTRACT: Based on the basic laws of non-Darcy seepage in low permeability media as
well as dynamic permeability, a dynamic function of permeability is derived. On
this basis, factoring in the effect of the non-linearity and the starting pressure
gradient, a piecewise numerical simulation model was established for low permeability
reservoirs and through discretization, a numerical model was obtained. According
to the results of the simulation test, this model and method reflect well the seepage
in low permeability reservoirs, expressing more objectively the influence of the
starting pressure gradient and the non-linearity.
