In the field of oil extraction, the pumping rod pump is the core equipment of mechanical oil production, and the operating stability of the rod pump directly determines the mining efficiency and economic benefits of the oilfield. However, in the actual mining process, sucker rod pumps often face the problem of underground water accumulation. Water accumulation will not only increase the operating load of the sucker rod, but may also cause problems such as partial wear of the rod and pipe, and decreased pump efficiency. In severe cases, it can even lead to equipment failure and shutdown. The emergence of tubing drain valves for oilfield has provided an efficient and feasible solution to solve the pain points of this industry, and has become an important supporting component to ensure the stable operation of the sucker rod pump.
Tubing drain valves for oilfield, as a drainage device designed for sucker rod pumps, its core role is to discharge the underground water generated during the work of the sucker rod pump in real time, and to reduce the adverse effects of stagnant water on the equipment from the root cause. When the sucker rod pump is in normal operation, the downhole crude oil will be extracted along with a certain amount of stagnant water. If the stagnant water cannot be discharged in time, it will form an effusion in the pump cylinder, causing the sucker rod to withstand additional liquid column pressure in the reciprocating movement up and down, increasing energy consumption. At the same time, it will also accelerate the wear between the sucker rod and the tubing. Through the unique structural design of the tubing drain valves for oilfield, the pressure difference can be used to quickly guide the stagnant water to a specific channel during the movement of the sucker rod, ensuring that a reasonable crude oil level is always maintained in the pump cylinder, effectively reducing the probability of partial wear of the rod and pipe, and extending the service life of the sucker rod pump.
In addition to reducing equipment wear and tear, tubing drain valves for oilfield can also significantly improve the working efficiency of sucker rod pumps. In the absence of tubing drain valves for oilfield, stagnant water will be mixed with crude oil to form an emulsion, which not only increases the viscosity of the crude oil, but also occupies the effective volume of the pump cylinder, resulting in a reduction in the amount of crude oil pumped in a single time, and the pump efficiency is greatly reduced. The tubing drain valves for oilfield developed by Dongsheng Petroleum adopt a dual-function design of high-precision filtration and high-efficiency drainage, which can not only quickly discharge stagnant water, but also prevent impurities in crude oil from clogging the drainage channel, ensuring that the sucker rod pump is always in efficient operation. Practical application data show that after installing tubing drain valves for oilfield, the pump efficiency of the sucker rod pump can be increased by 15%-20%, and the maintenance cycle of the equipment can be extended by more than 30%, which reduces a lot of production costs for oilfield companies.
In a complex underground environment, the reliability of tubing drain valves for oilfield is also critical. According to the geological conditions and mining needs of different oil fields, we have optimized and upgraded the material and structure of tubing drain valves for oilfield. The core components are made of high-strength corrosion-resistant alloy materials, which can resist the erosion of underground high temperature, high pressure and corrosive media; At the same time, the innovatively designed check valve structure effectively prevents the return of stagnant water and ensures the stability of drainage efficiency. Whether it is in high-water-bearing oil fields or complex oil and gas reservoir mining scenarios, our tubing drain valves for oilfield can maintain excellent working performance and provide a strong guarantee for the stable operation of the sucker rod pump.
As an enterprise focused on the research and development and production of oil extraction equipment, we have always been oriented to solving practical problems in the industry, and continue to promote the technological innovation of core supporting components such as tubing drain valves for oilfield. In the future, we will continue to combine intelligent technology to develop tubing drain valves for oilfield with real-time monitoring and adaptive adjustment functions, to further improve its adaptability and work efficiency in the pumping rod pump system, and to contribute more to oilfield enterprises to achieve efficient, energy-saving and low-cost mining. I believe that with the continuous improvement of tubing drain valves for oilfield technology, its role in sucker rod pumps will become more prominent, and it will become an important boost to promote the high-quality development of the oil extraction industry.
