Modeling of the fluid flow to the production well in the presence of discontinuities in the reservoir

摘要

Modelling of fluid flow through the fracture receives the more and more attention in applied geosciences from oil and gas industry. The fracture may be either artificial, in case of well simulation, or natural, in case of tectonic fault, and it may have different permeability. The steady-state flow process of incompressible fluid to the production well in a reservoir of constant height and permeability is considered in this paper. There is a thin area in the reservoir with constant permeability k_f, which might be highly permeable crack or low permeable barrier. The characteristic of filtration process is studied for various k_f value. The nature of fluid flow to the wellbore at different locations of the crack and the well for different values of the fracture conductivity F_(CD) is analyzed in this paper.
