Abstract:
A model of fluid filtration in the production well in the presence of craks of oil layer is built. These expansions can be both highly permeable and low-permeable and are characterized by the dimensionless ratio of conductivity of $F_{CD}$. For different values of $F_{CD}$ the nature of filtering process is investigated; factor of productivity of the well is defined, an analytical expression for the skin factor, which reflects the influence of fractures on the productivity of the well is obtained.
Keywords:fluid filtration, highly permeable fractures, low permeability, productivity factor of the well, well skin factor with fracture.
