From the prototype of machinery in the 19th century to today's intelligent and highly adaptable modern products, sucker rod pump has been continuously upgraded iteratively, and Tieling Dongsheng Petroleum Machinery Co., Ltd. has been in this industry for more than ten years. It is not only a witness to this historical process, but also a promoter of technological innovation. With its independent research and development strength, the traditional sucker rod continues to progress.
The history of sucker rod pump can be traced back to the middle of the 19th century. In the early days of the first commercial oil well in Pennsylvania in 1859, oil and gas extraction relied on simple extraction devices, which were inefficient and limited by the depth of the well. With the surge in demand for oil and gas, in 1875, American engineers first developed a “beam pumping unit sucker rod pump” combination device with a rod-column transmission structure. This is the prototype of the early sucker rod pump. This device drives the underground oil pumping rod through the ground pumping unit, drives the pump body to complete the oil suction and discharge action, and increases the mining depth from tens of meters to hundreds of meters, marking the official entry of sucker rod pump into the industrial application stage.
At the beginning of the 20th century, sucker rod pump ushered in the first technological innovation. With the development of the iron and steel industry, the material of the sucker rod has been upgraded from cast iron to high-strength carbon steel, the sealing structure of the pump body has been optimized, and the well depth has exceeded 1,000 meters, which is widely used in land oil fields around the world. In China, since the 1950s, our country has begun to independently develop sucker rod pump, from imitation to independent design, and gradually established a local production system, but limited by the technical level, early products have problems such as short life and low efficiency, making it difficult to meet the needs of complex oil and gas reservoir extraction.
Entering the 21st century, oil and gas extraction has moved towards complex working conditions such as deep wells, high temperature and pressure, and high viscosity, and sucker rod pump is facing more high-tech challenges. At this time, Dongsheng Petroleum came into being. At the beginning of the establishment of the company in 2012, with the goal of “breaking through the technical bottleneck of sucker rod pump”, relying on more than ten years of industry accumulation, a professional R&D team was formed to attack the pain points of traditional sucker rod pump.
In view of the problem that the sucker rod is easy to break and the pump body is easy to wear, Dongsheng Petroleum has continuously extended the average trouble-free operating cycle of sucker rod pump from the traditional 6 months to longer through continuous technological innovation. Facing the problem of high-viscosity oil and gas well mining, the team improved the design of the pump body flow channel and developed RWB sucker rod pump, which improves the suction efficiency of viscous media through a special valve group structure, which is much higher than traditional products, filling the technical gap of sucker rod pump for medium and high-viscosity wells in China.
Now, Dongsheng Petroleum's sucker rod pump products have formed a full range of matrices covering conventional wells, deep wells, and special media wells. They have not only passed international certifications such as API 11AX and API 11B, but have also become qualified suppliers of PetroChina and Sinopec, with an annual production capacity of more than 20,000 units. From the early mechanical transmission to the current material innovation and structural strengthening, every progress of sucker rod pump has promoted the improvement of oil and gas extraction efficiency, and Dongsheng Petroleum has always taken technological innovation as the core. While inheriting the historical and technological context of sucker rod pump, it continues to explore its application in the extraction of new oil and gas reservoirs, injecting new kinetic energy into the development of the industry.
In the future, with the integration of intelligent technology, Dongsheng Petroleum will further develop sucker rod pump that is more suitable for future development. It will provide real-time feedback on underground working conditions through built-in sensors to achieve remote operation and maintenance, so that the century-old sucker rod pump will continue to play a key role in the new era of energy development.
