Abstract

The relevance. Today, the production of oil is generally carried out in a mechanized manner, which is sufficiently energy intensive. In the cost structure of oil production, the value of electric power is from 30 to 35 % of the value. Considering that the submersible plants oil production is impossible without loss of power that is 20 to 40 % power consumption, the technology to increase the energy efficiency oil production has a high potential of embedding. One of the promising directions of electric power consumption reduction by submersible installations is the technology of submersible compensation. On the one hand, the introduction of the submersible compensator results in increase of the cost of purchase, maintenance, mobilization or hire of the submersible plant. On the other hand, the use of submersible compensator reactive power results in reduction of the cost of electric power and increase in production efficiency. The use of submersible compensators makes it possible to reduce the loss of active power in the power transmission system of the submersible installation by reducing the reactive component of the current submersible motor. However, with different technical characteristics of the submersible installation equipment, the effect of the submersible compensator will be different. In this relation, it should be avoided that the cost of introduction of the submersible compensators will be higher than the positive effect of introduction. It is necessary to determine the aggregate cost of possession of an electric centrifugal pump installation with a submersible compensator reactive power. The aim of the research is to analyze the reduction of current electric power consumption with the use of the installations electric centrifugal pumps with the submersible compensator reactive power. The object: portion of the power supply system of a cluster oil producing wells equipped with installations electric centrifugal pump. Methods: laws of electrical engineering theory, electric drive theory, simulation methods and technical-economic rationale. Imitation modeling of a portion of the power supply system of the well cluster is performed in a Software Complex of MatLab Simulink. Result. The paper describes the method of calculation of aggregate cost of possession of electric centrifugal pump with submersible compensator. The software model of the section power supply system of the well cluster is built in the MATLAB Simulink. It was found that the use of submersible compensators results in reduction in power consumption at the ownership of a submerged installation. The maximum reduction in power consumption on one of the test submersible units was 303,6 thousand rubles in year.
