Abstract
The paper is dedicated to the description and approbation of an algorithm to search the reasons of energy efficiency change for a group of artificial oil production wells. The approach is proposed, which is based on comparison of the specific energy consumption for two time periods and allows to distribute the total energy consumption among the equipment elements and to take into account the share of the influence of the reservoir, submergible and wellhead equipment of the well in the installation total change of the effective head and efficiency. The algorithm forms an address list of activities aimed at the energy efficiency improvement. The approbation of methodology was performed at the facilities ANK “Bashneft” PJSC.
Materials and methods
The digital twins of artificial oil well, which is equipped by the electric centrifugal and rod pump installations are used, which help to calculate the electric energy losses by the elements of the pump installation and their influence on the total efficiency. The refinement of the reasons of the pump head change by changes of well productivity, pump working regime, wellhead pressure, and hydraulic losses in the lift tubes and fitting is provided.
