System research and information technologies| Zusammenfassung: | Based on the complex analysis methods developed by the authors, an approach was developed for solving nonlinear boundary value problems of a non-isothermal multiphase filtration in the elements of flooding under conditions of the filtration flow perturbation by the hydraulic fracturing cracks. The numerical algorithm is constructed to calculate the hydrodynamic grid, the fields of temperature and saturation, the coordinates of critical points, the filtration rate of injection and production wells, the time of fracturing fluid penetration and complete flooding of wells. With this algorithm, we calculate the volume of fluid displaced during the specified amount of time and the corresponding volume remaining in the reservoir at any given time, in particular after stopping the injection, as well as determining the oil "stagnation" locations and the like. An analysis of numerical calculations of redistribution of the corresponding filtration characteristics was performed and the specific properties of the oil displacement process in cases of non-isothermal and isothermal filtrations were determined. |
