The relevance of the research is related to the effectiveness of monitoring dynamic operating modes of wells equipped with a frequency-controlled electric submersible pump at development and computational implementation of well system models operating in real time. Complex functionality of the solution introduced in the article allows reproducing the systems real forms of behavior in transient and equilibrium operation modes under the impact of complicating factors, which is the basis of the correct parametric estimation using real-time control data of well operating states. The main aim of the research is to construct a complex hydrodynamic model of the «reservoir–well–electric pump–wellhead» type, oriented to the tasks of complicated operating modes control of real-time systems. Objects: material balance, linear filtration, hydrostatics, linearized kinetics of friction losses, numerical modeling of differential equations. Methods. The constructed and implemented hydrodynamic model of electric submersible pump-equipped well reproduces a holistic and logical «portrait» of actual behavior of the system in transient and equilibrium operation modes under the impact of complicating factors. The simplified nature of model components and connections descriptions allows the implementation and usage of functionally updated monitoring applications within the information resources of the enterprise. Results. Complexity and factor wholeness of the model description are the basis for designing algorithms and regulations for parametric identification and subsequent recognition of the types and levels of impacting complications on system using actual operation data. The implementation of the computational process in sync with the dynamics of state and disturbances control data update make it possible to use the model as a virtual measure of the extended vector of well states in transient and steady-state operating modes.
