    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.

    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.

    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.

    Carbon fiber sucker rod centralizer uses carbon fiber and ultra-high molecular polyethylene, which have the advantages of light weight, high strength, high modulus, low density, high temperature resistance, corrosion resistance, etc. As raw materials. It is processed and molded by injection molding and other methods to effectively alleviate the frequent workover problems caused by well pipe wear and fracture. Its wear resistance is more than 5 times that of nylon centralizer.
