The Influence of the Reservoir Discontinuities on Fluid Filtration to the Production Well
Authors: ,
Abstract: Today especially important to study the filtration process in the reservoir with fractures. The fracture may be either natural, in case of tectonic fault, or artificial, in case of well simulation, and it may have various permeability values. This paper considers the steady-state flow process of incompressible fluid to the production well in a reservoir of constant height and permeability. There is a thin area in the reservoir with constant permeability kf, which might be highly permeable crack or low permeable barrier. The characteristics of filtration process are studied for various kf values. The nature of fluid flow to the wellbore is analyzed at different locations of the well and the crack for different values of the fracture conductivity in this paper and the analytical expression for skin effect is defined.
