Annotation:
The article presents the methods and results of hydrodynamic modeling of intra-layer processes of suffusion and removal of solid rock particles that occur during flooding of unconsolidated reservoirs with high-viscosity oil. Using the example of one of the deposits, it is shown that the proposed modeling approaches allow reproduction of the actual non-classic dynamics of unconsolidated reservoir development indicators without the use of anomalous modifications of the influencing parameters. The results of numerical calculations on the influence of the model parameters of solid rock particle suffusion on the main development indicators confirm the need to take these effects into account when designing the development of unconsolidated reservoirs with high-viscosity oil.
