Abstract
Implementation of energy saving measures is impossible without reliable assessment of energy efficiency indicators of operating process equipment of the entire complex and its facilities. The article proposes an algorithm for calculating these indicators in relation to reservoir pressure maintenance systems (PMS) at oil production facilities. The most energy consuming equipment of PMS systems are pumping units for various purposes: high-pres-sure pumps for pumping water into the reservoir, low-pressure back-up pumps, submersible electric centrifugal pumps for water extraction wells for PMS, and others, depending on the particular process scheme. The paper considers the factors influencing the formation of energy efficiency indicators, as well as the parameters necessary for the calculation, taking into account the limitations of the primary source data and the frequency of their collection. The developed algorithm determines the methodology for calculating such significant indi-cators as actual and normative power consumption, actual and normative specific power consumption for a separate pumping unit and the entire pump block, the actual efficiency of the pumping unit and the pump block, and, as a consequence, the current energy effi-ciency of the pump unit and the pump block as a whole. The proposed algorithm can be implemented in an information and analytical program to automate the calculation process with the required periodicity and issue calculated data for the formation of analytical information and plan further actions to take measures to improve efficiency.
