In the process of crude oil extraction, sucker rod pump barrel leakage is a common problem, which not only causes delays and energy waste, but also may cause problems such as liquid hammer and vibration, and accelerate the damage of components such as plungers and valve groups. Pollute the well site environment and even cause fire hazards. So, what causes pump barrel leakage? How should we effectively reduce pump barrel leakage?
In the process of crude oil extraction, the excessive pressure generated by the reciprocating motion of the plunger in the rod pump barrel is a major factor leading to sucker rod pump barrel leakage, because this will cause the pressure difference between the upper and lower pump chambers in the rod pump barrel to be too large, resulting in crude oil leakage. If the upper and lower valves of the sucker rod pump are not tight, it will also directly lead to the leakage of crude oil in the pump barrel. During the regular maintenance and repair of the sucker rod pump, if the maintenance and inspection are not meticulous, there may be a potential risk of damage to the rod pump barrel. At the same time, collisions during maintenance, excessive pressure differences or improper installation of the plunger may cause cracks in the pump barrel, which in turn causes crude oil leakage. Of course, in addition to the above reasons, pump barrel crude oil leakage may also be affected by factors such as hot washing cycle, sand flushing process, pipeline flushing and oil properties of pump barrel.
Therefore, in the process of crude oil collection, we must pay close attention to these problems and take effective measures to prevent and solve them. First of all, we should strengthen the work quality of sucker rod pump crude oil collection process, cultivate employees' sense of responsibility, increase the training of professional talents, and improve the overall quality of the team, so as to reduce the leakage caused by work errors. At the same time, in order to ensure the smooth progress of crude oil collection process, each collection team should be equipped with full-time personnel to track and guide oil production operations and monitor the whole process. In addition, it is necessary to reasonably optimize the pressure and friction force parameters in the rod pump barrel to reduce damage to the pump cavity, so as to prevent crude oil leakage caused by rod pump barrel damage.
In order to further enhance the durability of sucker rod pump barrel, our company uses advanced science and technology to optimize the internal structure of sucker rod pump. For example, we use electroplating technology to plate a layer of chrome on the inner surface of the rod pump barrel, and use the excellent properties of chrome (such as non-immersion in water, non-immersion in oil, and corrosion resistance) to improve the flatness and finish of the inner surface, etc., and improve the performance of the sucker rod pump in various ways. The sucker rod pump produced by our company has passed the ISO 9001 quality management system certification and obtained the API11AX certificate use license. Our company's products include more than 100 sucker rod pump products and accessories such as sucker rod pump, long plunger anti-sand pump, oil drainer, stabilizer, gold-sprayed plunger, centering, and integrated grinding. We have established a complete testing system to implement full process control and testing from raw materials, semi-finished products to finished products.
