On December 13, Feng Chunguo, director of the machinery factory at Shenyang New City Petroleum, revealed that Daqing Oilfield had recently placed an order for ten submersible electric pumps on a corporate account and was urgently awaiting delivery. Just hours earlier, representatives from Shengli Oilfield had visited to discuss the purchase of similar equipment. The reason behind this sudden surge in interest? The factory's newly developed patented product—the "Rodless CNC Reciprocating Submersible Electric Pump"—has created quite a buzz in the industry. Located in Liuwang Village, Xinchengzi District, Xincheng Petroleum Machinery Factory is a joint-stock enterprise founded in the early 1990s. For over two decades, under the leadership of farmer-turned-entrepreneur Feng Chunguo, the small factory has continuously innovated and improved its products, gradually improving its performance and profitability. Feng has always been keenly aware of the inefficiencies in traditional oil production methods and has focused his efforts on solving these challenges. Most oil extraction systems still rely on surface-mounted power units, commonly known as "steamers," which use long sucker rods to lift oil from deep underground. This method is energy-intensive, requires frequent maintenance, occupies large amounts of land, and suffers from low efficiency and limited production capacity. Three years ago, Feng had an idea: what if the power unit could be placed underground instead? After extensive research and multiple trials, he successfully developed the "Rodless CNC Reciprocating Submersible Electric Pump" based on magnetic levitation technology. The product was granted a national utility model patent. In December of last year, after successful ground simulation and performance testing, the first unit was deployed in Daqing Oilfield, with impressive results. The production per well increased by nearly 30%, daily power consumption dropped by over 40%, and the investment cost per well was reduced to just 47,000 yuan. This breakthrough not only addresses long-standing issues in the industry but also marks a significant step forward in oil extraction technology.
