Annotation:

The article describes an aggregated model of an oil field, which allows determining the main technical and economic indicators of oil production in the dynamics for the future and allowing the study by optimal control methods. The main problems of the oil industry are considered, the necessity of using simulation and approximating models for modeling the development of oil fields is justified. The approximating model of a field is described in detail in the form of a system of ordinary differential equations linking, in particular, oil production, production and injection well stocks, wells flow rates, and the water cut coefficient. The issues of accounting for production rates and the features of the model for various stages of field development – the stages of growth and stable production, the decline in production when new wells are commissioned and without their commissioning are specified. The various dynamic indicators being formed are listed – technological, economic, social development and financial situation. The issues of modeling and optimization for a group of oil fields are considered, as well as the features of the software implementation of the model.
