摘要

This paper presents the results of numerical calculation of gas filtration in a low-permeability gas formation with a fractured well. It is assumed that in the low-permeability formation and in the finite-conductivity fracture is described by the Darcy law. The Peng-Robinson equation was used to take into account the dependence of the PVT properties of the gas on pressure. We studied the effect of fracture conductivity and formation permeability on the distribution of pressure and gas properties in the fracture-formation system and on the dynamics of well pressure and gas production rate during gas well testing.
