In the field of oil extraction, tubing pump, as a mature and reliable mechanical oil production equipment, continues to provide the core driving force for stable oilfield production. Tieling Dongsheng Petroleum Co., Ltd. has been deeply engaged in the research and development and manufacturing of oil production equipment for more than ten years. Relying on structural optimization and technological innovation, its tubing pump series products have been applied on a large scale in many domestic oilfield blocks, effectively supporting the development needs of old wells to increase production and new wells to improve efficiency.
1. The core technical advantages of tubing pump：
The tubing pump adopts an integrated design of pipe and column, which directly connects the pump body to the bottom of the tubing. This structure omits the independent working cylinder required for conventional oil pumps, greatly reducing the complexity of the well. Its core working principle is to drive the reciprocating movement of the pumping rod through the ground pumping unit, drive the downhole pump valve to open and close, and form a lifting cycle of negative pressure suction and positive pressure discharge of crude oil. Compared with traditional oil pumps, tubing pump has three outstanding characteristics：
The failure rate is significantly reduced: The simplified flow channel design reduces the risk of sand stuck and air lock, and is suitable for well conditions with high sand content and high gas-oil ratio.；
Extended pump inspection cycle: The integral pump cylinder structure avoids the failure of threaded connection points, and the average maintenance interval is increased by more than 30%.；
Optimization of production efficiency: The fixed anchoring link is eliminated, and the operating time is shortened by 20%, which is particularly suitable for rapid production.
2. Application scenarios of tubing pump：
Tieling Dongsheng's tubing pump product line covers a variety of specifications and can match different production needs：
Low permeability reservoir: Small pump diameter tubing pump achieves stable liquid extraction from an average of 5-30 cubic meters per day to alleviate the pressure-sensitive problem of the reservoir.；
High water content development period: Corrosion-resistant coated pump cylinder should cope with high mineralization and produce water to ensure the continuous operation of the system；
Marginal benefit well: The low-impulse operation mode is combined with frequency conversion control to reduce the energy consumption of tons of oil by 15% and activate the value of stock resources.
3. Improvement of tubing pump in the era of intelligence：
In order to maximize the service efficiency of tubing pump, Tieling Dongsheng has simultaneously built a "three-stage preventive maintenance system".：
Precision inspection before entering the well: A laser diameter gauge is used to fully check the roundness of the pump cylinder to ensure that the gap is ≤0.08mm；
Early warning of parameters in operation: real-time monitoring of pole and column stress through load sensors, automatic identification of early signs of Verne leakage；
Root cause analysis after failure: establish a database of failed parts and optimize the heat treatment process of the material in a targeted manner.
This system enables the average trouble-free operation of tubing pump for up to 14 months, which is 25% higher than the industry benchmark, and has become a key support for cost reduction and efficiency enhancement in oil fields.
4. Technological evolution and industrial collaboration：
With the acceleration of the construction of smart oil fields, a new generation of tubing pump is integrating Internet of Things technology to achieve breakthroughs：
Embedded pressure sensor enables dynamic diagnosis of pump efficiency；
Nano tungsten carbide coating breaks through the bottleneck of wear-resistant life；
The modular design supports rapid underground replacement.
As a classic solution in the field of mechanical oil recovery, tubing pump, with its structural simplicity, adaptability to working conditions and cost controllability, continues to play an irreplaceable role in scenarios such as unconventional resource development and secondary oil recovery in old oil fields. Tieling Dongsheng Petroleum Co., Ltd. will promote the iterative development of tubing pump technology in the direction of high efficiency, long life and low maintenance through the triple path of material innovation, process upgrading and intelligent operation and maintenance, so as to provide a solid equipment guarantee for China's energy security strategy.
