description: In the work, simulation of unsteady flow in the integrated system "bottomhole zone of a well - well - installation of an electric centrifugal pump" was carried out. Tasks that were solved during the study: 1. Review of the discovered reservoir modeling methods (bottomhole zone) to describe the inflow to the well. 2. Review of current approaches in the field of modeling non-stationary processes. 3. Review of repeating types of correlations in the field of well flow modeling. 4. Analysis of the main physical properties that affect the mixture in wells and non-stationary processes. 5. Analysis of non-stationary processes and their classification. 6. Development of a simplified reservoir model. 7. Development of a model of unsteady flow in a well. 8. Development of a model for the installation of an electric centrifugal pump. A mathematical model of the unsteady flow of a gas-liquid mixture along the wellbore was proposed based on a mechanistic approach. The results of the work algorithm were compared with simulations in commercial software and with actual measurement data. The proposed model can be used to model wells for regime, for wells with stable energy inclusion and for wells with an unstable lifting curve.
