“…На сегодняшний день на подъем жидкости из скважины, вертикальная глубина которой может достигать 2,5-3 км, приходится порядка 60% всей энергии, потребляемой нефтедобывающим предприятием, даже с учетом наличия таких энергоемких процессов как поддержание пластового давления и сбор, подготовка и транспорт нефти. В связи с этим особенно важно обеспечивать требуемую энергетическую эффективность процесса добычи нефти на механизированном фонде скважин, что на практике реализуется оптимальным подбором погружного оборудования -его энергосберегающим дизайном, в соответствии с геолого-техническими условиями, в которых осуществляется добыча [2,3].…”

When solving the problem, the method of factor analysis of specific power consumption, implemented in a model, was used.RESULTS. The article describes the relevance of the topic, considers the features of the use of various indicators of energy efficiency. A model of factors for specific power consumption has been developed. In this article, a concept of an automated energy efficiency control system based on intelligent methods has been proposed. CONCLUSION. Using the indicator of specific electricity consumption for artificial oil lift, as an indicator of energy efficiency, makes it possible to assess the current level of energy efficiency and identify the potential for further energy saving.

“…As the key equipment for the supply of high head liquids, ESP can meet the requirements of different flow conditions and is now widely employed in the field of marine oil extraction. [1][2][3] In China, ESP accounts for 90% of oil production from the offshore oil field. [4][5][6] The working environment of ESPs is deep-sea oil field, which makes it highly difficult for the maintenance and repair during the process of usage.…”

Electrical Submersible Pumps (ESP) are one of the most reliable and efficient ways to lift oil or water from the ground or deep-sea to the surface. How to reduce the pressure pulsation and increase reliability is a challenging issue in the ESP design processes. In this study, a typical three-stage ESP model was selected as the research object. Based on numerical calculations and validation tests, the flow-field distribution mechanism within the dynamic and static interference zones of multi-stage ESP was investigated. Meanwhile, the inter-stage variability of pressure pulsation characteristics within the main hydraulic components was explored by Morlet continuous wavelet transform. The results showed that the numerical predicted performance has an excellent agreement with the experimental results, which confirms the accuracy of the numerical calculations. The time-domain characteristics of pressure pulsation at each monitoring location within the ESP showed high disorder due to the inter-stage propagation and coupling of the pressure pulsations. The low-frequency signal in the pressure pulsation signal had not only a cascading superposition of intensity, but also a significant phase difference. It was found that the main form of propagation between pulsating signal levels is the low-frequency signal. This work may facilitate the reduction or control of the pressure pulsations and thus improve the operation stability of ESP.

“…There are 2 wells utilizing the progressive cavity pump system, accounting for 4.94% of the total w In comparison to the beam pump system, the progressive cavity pump system en lower initial investment and maintenance expenses. It is commonly employed in offsh wells and is well-suited for wells containing heavy oil, sand, or exhibiting a high gas ratio (GOR) [43]. However, the rubber stator is more susceptible to damage, leadin increased maintenance requirements.…”

In recent years, companies have employed numerous methods to lower expenses and enhance system efficiency in the oilfield. Energy consumption has constituted a significant portion of these expenses. This paper introduces a normalized consumption factor to effectively evaluate energy consumption in the oilfield. Statistical analysis has been conducted on nearly 45,000 wells from six fields in China. Critical factors such as lifting method, daily production, pump depth, gas–oil ratio (GOR), and well deviation angle were evaluated individually. Results revealed that higher production could lead to lower normalized consumption for beam pumps, progressive cavity pumps, and electric submersible pump systems, thus enhancing system efficiency. Additionally, a higher GOR might result in lower normalized consumption for the beam pump system, while the deviation angle of the well showed negligible impact on the normalized consumption factor. This manuscript offers a method to assess the impacts of artificial lift methods on production and discusses suggestions for reducing consumption associated with each lifting method in the oilfield.
