Dongsheng has been established for more than ten years, and our team has been dealing with API subsurface rod pumps for a long time. Every time a customer asks us why many old wells and low-yield wells will eventually choose API subsurface rod pumps to maintain production, I always say that it is not because we sell a lot, but because this equipment is really durable.

The API rod pump is one of the equipment in the artificial lifting system of the oil well. The lowering process is directly related to the stable operation and production efficiency of the entire oil production system. In order to reduce the occurrence of downhole failures and extend the service life of the equipment, standardized lowering operation cannot be ignored. This article combines our product features and industry experience to systematically explain the API rod pump lowering operation procedure and give a reasonable explanation for each operation.

There are many factors that affect pump efficiency, but from the three basic links of the deep-well sucker rod pump (the piston gives up volume, crude oil enters the pump and is discharged from the pump), it can be summarized into the following three aspects.

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.

On November 5, 2024, a customer team from Russia visited the factory and conducted on-site visits and exchanges on our production base and core products: API type rod pump, API type tubing pump, etc. This visit not only deepened our cooperative relationship, but also once again verified the superior performance and reliability of our products in extremely cold areas.

Recently, a delegation from China Petroleum Material Procurement Center visited our company for inspection and exchange. Company leaders and relevant persons in charge attended. China National Petroleum Corporation (hereinafter referred to as "China Petroleum") was established on February 9, 1990. It is an important state-owned backbone enterprise and one of the world's major oil and gas producers and suppliers. It plays an important role in the global energy industry.

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!
