Abstract

In recent years, the oil industry has grappled with persistently low oil prices, a surge in low-producing wells, and the continued erosion of oilfield extraction efficiency. The global count of operational pumping wells in oilfields has surpassed 2 million. Currently, both domestic and international oil production predominantly relies on mechanical pumping systems [1], wherein pumping machines supply the mechanical power required for oil extraction. This method prevails across most oilfields [2-4]. Among the various mechanisms employed, the swimming beam pumping machine stands out for its simplicity, ease of maintenance, and reputation for stability and reliability. However, it lags in terms of extraction efficiency, with an average range of only 12% to 23% [5,6]. This deficiency poses a significant hurdle to the economic development of oilfields and energy conservation initiatives. To address these challenges and significantly enhance energy efficiency while reducing emissions, we propose the design of a single-drive multi-well pumping machine [7]. The innovative single-drive multi-well pumping machine employs a load distribution mechanism that effectively eliminates the inefficient load (pumping rod weight) from the system while ensuring that alternating loads are uniformly distributed. This approach rectifies the issues of irregular force sinusoidal fluctuations, high energy consumption, and inefficiencies inherent in traditional swimming beam-type pumping machines. Consequently, it results in substantial energy savings of 65% to 80% and cost reductions of 65% to 75% when compared to similar models.
