In global oil extraction, the rod pump is one of the most crucial artificial lift systems, widely deployed in onshore oil fields, heavy oil wells, deep wells, and highly corrosive environments. To improve well production, reduce well shutdowns, and extend pump lifespan, selecting a high-quality, API 11AX-compliant sucker rod pump is essential. Dongsheng, a leading domestic manufacturer of sucker rod pumps, leverages its factory-direct sales, stable quality, and technical expertise in partnership with SLB to continuously provide global customers with highly reliable API pump, downhole pump, and oil well pump solutions.

In oil exploration, the adaptability of sucker rod centralizer directly determines whether it can be stable and anti-wear and anti-stuck in different well types and complex well conditions. The columnar sucker rod centralizer developed by Dongsheng Petroleum, relying on structural and material innovation, breaks through the limitations of traditional equipment “single adaptation” and realizes flexible matching in multiple scenarios. We analyze the adaptation advantages of this sucker rod centralizer from the three dimensions of well type, well condition, and installation, and show its ability to support different mining scenarios.

I. The Crucial Role of Rod Pump Barrels in the Oil Extraction Industry Oil, as a vital resource for global economic development, has long held a pivotal position in the energy structure. Whether in transportation, chemical raw materials, or power generation, oil and its derivatives remain an indispensable energy source for modern society. Despite the rapid development of new energy technologies, oil extraction will continue to be a crucial pillar of global energy supply in the foreseeable future.

In the operation of the sucker rod pump, the centralizer is a key component to avoid partial wear of the rod and ensure the stability of the equipment. Spiral sucker rod centralizer and standard sucker rod centralizer are common types in oil fields. The two have significant differences in structure, application scenarios and performance. The following is a detailed analysis of the differences based on our Dongsheng Petroleum experience and standards.

Complex underground working conditions, high temperature, high pressure, medium corrosion and high-frequency friction between components often cause damage to the internal structure of the sucker rod pump and affect the service life of the equipment. As an important core component of the sucker rod pump, cages for downhole pump relies on its own performance to provide a reliable solution to this problem and has become the key support to ensure the efficient operation of the sucker rod pump.

In the field of oil extraction, the pumping rod pump is the core equipment of mechanical oil production, and the operating stability of the rod pump directly determines the mining efficiency and economic benefits of the oilfield. However, in the actual mining process, sucker rod pumps often face the problem of underground water accumulation. Water accumulation will not only increase the operating load of the sucker rod, but may also cause problems such as partial wear of the rod and pipe, and decreased pump efficiency. In severe cases, it can even lead to equipment failure and shutdown. The emergence of tubing drain valves for oilfield has provided an efficient and feasible solution to solve the pain points of this industry, and has become an important supporting component to ensure the stable operation of the sucker rod pump.

In oil extraction lifting systems, the performance of spiral sucker rod centralizer is determined by the structural design. A high-quality spiral sucker rod centralizer needs to take into account the convenience of installation, adaptability to working conditions and durability through a scientific combination of components. Dongsheng Petroleum has extensive experience in the structural adjustment of spiral sucker rod centralizer. We will take you to understand the mystery of its structure from the three aspects of core components, material logic, and adaptation advantages.​

In oil extraction, the material selection of spiral sucker rod centralizer directly affects the operation and maintenance cost and production efficiency of oil wells. The performance of spiral sucker rod centralizer of different materials is obviously different, and its core value can only be realized by combining the scientific selection of well conditions. We, Dongsheng Petroleum, have been engaged in the field of oilfield equipment for many years and have conducted in-depth research on the application characteristics of spiral sucker rod centralizer of various materials. We will start from the three mainstream materials of metal, polymer, and composite materials, analyze the advantages and disadvantages of different materials and applicable scenarios, and provide a reference for oilfield companies in the selection of types.

In oil extraction, the core value of sucker rod centralizer is to balance anti-wear protection and operational safety-not only to reduce the friction between the sucker rod and the tubing to extend the life of the equipment, but also to avoid stuck well accidents. Stuck wells will directly interrupt production and cause chain failures. If the sucker rod centralizer configuration is simplified to avoid stuck wells, the anti-wear effect will be lost. Based on global service experience, Dongsheng Petroleum has summarized the whole process solution to help customers balance the two. We explain it from four dimensions.

Why are oil rod pumps so crucial and irreplaceable in oil production? In the middle and late stages of oilfield development, formation energy declines, and crude oil can no longer flow to the surface on its own. Mechanical means must be used to lift the oil. Among all mechanical oil production methods, rod pumping is the most mature and widely used, accounting for over 60% of global onshore oil well production. Without the economical and reliable mechanical lift methods represented by oil rod pumps, sustained and stable commercial production would be impossible. So, how does this globally used rod pump system continuously lift crude oil to the surface?
