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.
The core role of cages for downhole pump is to accurately fix and stabilize the moving parts inside the sucker rod pump, so that the components work together. During the operation of the sucker rod pump, the plunger needs to perform high-frequency reciprocating movement in the pump cylinder. If a stable support structure is lacking, the components are prone to offset and shaking, which will not only reduce the pumping efficiency, but may also cause serious mechanical failure. The cages for downhole pump developed by Dongsheng Petroleum adopts high-precision processing technology, which can closely fit the gap between the pump barrel and the plunger, and firmly fix the key internal components on a preset trajectory, effectively avoiding the problem of increased wear caused by component offset, so that the motion accuracy of the sucker rod pump is always maintained at the best condition, fundamentally improving the stability of equipment operation.
Reducing component wear and extending the service life of the sucker rod pump is another important role of cages for downhole pump. In the underground environment, impurities and corrosive media in crude oil will continue to erode the internal components of the sucker rod pump, and direct friction between the components will accelerate the loss. Through its own high-strength and high-wear-resistant material characteristics, cages for downhole pump forms a strong protective barrier between the pump barrel and the plunger, transforming direct friction into low-friction contact between cages for downhole pump and the components.We use special alloy materials to build cages for downhole pump. The surface has been specially hardened and has excellent wear resistance. It can greatly reduce the wear of components, significantly extend the maintenance cycle of the sucker rod pump, and reduce the cost of equipment replacement and maintenance for oilfield companies.
In addition, cages for downhole pump can also improve the impact resistance and corrosion resistance of the sucker rod pump, and adapt to complex underground working conditions.In the mining of deep and ultra-deep wells, the underground environment puts forward extremely high requirements for the tolerance performance of equipment components, and cages for downhole pump not only has excellent mechanical strength, but also has passed strict corrosion resistance tests. It can work stably for a long time in harsh environments, effectively resist pressure shocks and medium corrosion, and avoid the shutdown of the sucker rod pump due to the failure of the cage.In practical applications, our cages for downhole pump's sucker rod pump has been installed, which has greatly improved its reliability in difficult mining scenarios, providing a strong guarantee for the continuous production of oil fields.
As an enterprise deeply engaged in the field of petroleum extraction equipment, we have always taken technological innovation as the core and continuously improved the performance and structure of cages for downhole pump. In the future, we will combine big data on downhole working conditions to further develop customized cages for downhole pump adapted to different mining scenarios, and integrate intelligent monitoring functions to give real-time feedback on the operating status of cages for downhole pump to help oil fields achieve more efficient and safer mining operations. I believe that with the continuous upgrading of cages for downhole pump technology, the role of sucker rod pumps will become more prominent, injecting new impetus into promoting the high-quality development of the oil extraction industry.
