INFLUENCE OF BRAKING OF LAYER ON THE CHARACTER OF THE PROCESS OF FLUID FILTRATION TO THE PRODUCTION WELLS

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 Fcd . For different values of Fcd 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.
