Study of filtration processes of a two-phase fluid in a zonal-inhomogeneous fractured-porous medium

Abstract

Abstract A significant amount of proven reserves of hydrocarbons are contained in the fields to some extent have fracturing. Fractures have high conductivity, and, therefore, have a significant impact on the process of extracting oil from the reservoir. In this regard, it is necessary to investigate the filtration processes of a mixture of water and oil in fractured-porous reservoirs. In this paper, the task of selecting options for the appointment of injection and production wells in a zonal-inhomogeneous fractured-porous reservoir to the most complete extraction of oil from the reservoir. A study was also made of the influence of the intensity of water injection on the efficiency of oil recovery from a fractured-porous reservoir. The tasks were solved using our own three-dimensional two-phase hydrodynamic simulator based on the model of dual porosity-permeability.
