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.
Well type adaptation：
Traditional sucker rod centralizer is often adapted to a certain type of straight or directional well due to its single structure, which increases procurement costs. And our columnar sucker rod centralizer, through the combination of spiral grooves and elastic structure, realizes “one universal”. In a straight well, the symmetrical spiral groove evenly disperses the weight of the sucker rod to prevent partial wear, and the large sedimentation channel prevents sand accumulation; The oblique section of the directional well is made, and the slight elasticity of the columnar righting sleeve can adapt to the trajectory of the borehole, reducing the collision with the casing coupling, not only to ensure the anti-wear effect, but also to avoid the risk of getting stuck in the well. Whether it is conventional mining of shallow straight wells or complex operations of deep directional wells, it can be stably adapted without repeated purchases due to well type.
Well condition adaptation：
The well conditions of different oil fields vary greatly, and the sand content, corrosion resistance, temperature, etc. have diverse performance requirements for sucker rod centralizer. Our columnar sucker rod centralizer relies on dual-material righting sleeves and sand-proof design to achieve precise adaptation: in high-sand-containing wells, spiral grooves and large sedimentation channels guide the discharge of sand particles to prevent sand from getting stuck; Acidic and highly corrosive wells, metal spray welding material righting sleeves resist hydrogen sulfide and carbon dioxide, and extend the life of sucker rod centralizer; medium and shallow conventional wells, nylon material righting sleeves rely on low coefficient of friction to reduce energy consumption and wear, and are suitable for low maintenance requirements. Moreover, metal spray welding is high temperature resistant and nylon is suitable for room temperature. The two materials cover the temperature range of most well conditions, allowing sucker rod centralizer to cope with different environments without frequent replacement.
Installation adaptation：
The installation adaptability of sucker rod centralizer directly affects the construction efficiency and stability. Our columnar sucker rod centralizer adopts a pressure die-casting straight-mounted design and can be installed directly on the pumping rod body without complex welding or additional tools, greatly shortening the installation time; With the fixed structure of the lock mother, it can be firmly fixed between the lock blocks of the rod body to prevent loosening and shifting during operation. Whether it is a batch installation of a new well or a single replacement of an old well, this sucker rod centralizer can be quickly adapted to the scene. In addition, the standardized size design is compatible with different specifications of sucker rods, and there is no need to customize the size of the rod body to further improve the adaptability of installation and reduce the pressure on oilfield procurement and inventory.
Dongsheng Petroleum's columnar sucker rod centralizer breaks the traditional limitations with multi-dimensional adaptability and meets the needs of oil fields in all directions. which has passed the dual certification of ISO9001 and API 11AX, has been exported to many countries to verify its adaptation advantages. We always take customer needs as the core, and continue to enhance the adaptability of sucker rod centralizer to provide efficient and reliable mining solutions for global oil fields to help reduce costs and increase production.
