Definition of sucker rod pump: Sucker rod pump is a common downhole device that is driven by a pumping unit to pump crude oil from the well to the ground. The ordinary sucker rod pump is mainly composed of four parts: pump barrel, suction valve, piston, and discharge valve. According to the way the sucker rod pump is fixed underground, it can be divided into tube pump and rod pump.

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?

Due to the continuous development of industry and economy, the exploitation of oil wells has continued to increase, and the demand for sucker rod pumps has also continued to increase. Sucker rod pump is the main equipment in the rod pumping system. Depending on the depth of the oil well, production capacity, and crude oil properties, the required type of sucker rod pump structure will also be different.

In the actual oil production process of API sucker rod pump, the coordinated reciprocating motion of pump barrel and plunger is the key. This motion not only determines the displacement of API sucker rod pump, but also is affected by multiple factors such as plunger outer diameter, pump barrel inner diameter, pressure, temperature and axial force, which together determine the service life of API sucker rod pump. This article will take you to understand the working principle of API sucker rod pump in depth, thereby improving your efficiency in oil production.

In the world of oilfield exploitation, the oil well pump is like the "heart" of the oil well. Its performance determines the output and exploitation efficiency of crude oil. Among the many oil well pumps, the competition between API tubing rod pumps and API sucker rod pumpshas never stopped. One has a simple structure and large displacement, while the other is convenient for pump inspection and adaptable to deep wells. But what are their advantages and disadvantages? Which pump is more suitable for your oil well? Today, we will analyze these two oil well pumps in depth!
