The relevance of the paper is determined by the need to improve oil production and it is caused by geopolitical, economical and geological factors. The most important problem is to improve functional characteristics of mechanized oil production systems because of their high power consumption. Nowadays the idea of intelligent well technology is widely used to solve the problems at oil production. It is implemented by using control, information and telecommunication systems, and the adjustable equipment. When developing control system it is necessary to provide achievement of global result such as the cost reduction of oil production. Therefore, it is necessary to apply the principles of system approach, and economic criteria to estimate system efficiency. The main purpose of the research is to improve functioning of electrotechnical installations of mechanized oil production using the system approach to control. The methods used in the study: the systemic analysis of tendencies in using control, information technologies and the adjustable equipment in oil production industry; synthesis of technical and economic decisions; methods of mathematical modeling. The results. The authors have developed the strategy of controlling the of electrotechnical installation operating modes in mechanized oil production. It allows optimizing oil production in real time as economically effective one. Conclusion. The modern potential of information technologies and adjustable oil production equipment is not fully used. The contradiction between opportunities of such equipment and their real using can be overcome by application of system approach to control the installations where economic criteria are the main indicators of effective functioning of the systems.
