In the field of petroleum extraction, the rod pump oil recovery system has become the most widely used manual lifting method due to its high adaptability, simple structure and easy maintenance. As the core equipment of the system, API tubing pump occupies an important position.

Downhole sucker rod pump generally refers to a plunger-type oil pump driven by the reciprocating movement of the sucker rod up and down. It is the key underground equipment of the rod pumping system. It is mainly composed of four parts: pump cylinder, plunger, fixed valve and swimming valve. When working, the ground pumping unit drives the plunger up and down through the pumping rod.

In the global energy industry system, the efficiency and stability of oilfield extraction are directly related to the security of energy supply and the economic benefits of the industrial chain.However, the oilfield mining environment is complex and harsh, with high temperature, high pressure, high sulfur-containing media, and frequent wear and impact, making the core mining equipment face serious challenges.As an efficient equipment developed for extreme mining environments, RWA API Insert Pump are gradually becoming the mainstream choice in the field of oilfield mining due to their unique structural design and material advantages.

RWA Insert Rod Pump is a rod-type oil pump designed according to API SPEC 11AX (or GB/T18607) standard. According to the support and fixed form of the pump, it can be divided into three categories: moving cylinder type bottom fixed rod type oil pump (RWT or RHT), fixed cylinder type bottom fixed rod type oil pump (RWB or RHB or RXB), fixed cylinder type top fixed rod type oil pump (RWA or RHA).

Welcome to this issue's popular science column. When you think of oil, you probably think of gas stations, cars, and fluctuations in international oil prices. But have you ever wondered what form these oil and gas, often called the "blood of industry," actually take deep underground? And how are they extracted scientifically?

Maintaining efficient and stable crude oil production in environments with sand content, low liquid levels, deviated wells, and intermittent production has become a focus of industry attention. As a core piece of equipment in traditional mechanical oil production, the insert rod pump exhibits wide adaptability due to its diverse structural configurations. Among them, the top-fixed insert rod pump with a fixed barrel, the bottom-fixed insert rod pump with a fixed barrel, and the bottom-fixed insert rod pump with a moving barrel each play an important role in different operating conditions due to their unique structural advantages.

In the previous article, we discussed the RHA Insert Rod Pump. This article will explain the definition, model description, technical specifications, structural components, operating principle, application scenarios, comparison with other pump types, and installation methods of the TH tubing pump.

During oil production, when reservoir energy is insufficient to support natural crude oil flow, artificial lift systems become essential. Among these, RHA insert rod pumps are widely used worldwide. This article will explain the differences between different RHA insert rod pump models, including their structural components, operating principles, typical applications, technical differences compared to other pump types, and installation methods.

In the field of global oil extraction, lifting technology, as the key driving force of crude oil from underground to the ground, has always been the cornerstone of industrial development. Among them, the lifting technology of the beam-type pumping unit and the lifting technology of the electric submersible pump have become the mainstream choices for oilfield production due to their wide application and reliable performance. The evolution of these two lifting technologies has not only improved the mining efficiency, but also demonstrated the intelligent transformation of modern energy equipment.

Whenever an oil well is unable to lift crude oil to the ground autonomously like a tired old man, engineers activate artificial lift technology. Gas lifting is one of the most commonly used methods. Does it count as artificial lift technology? The answer is very clear: yes, gas lifting is not only an artificial lift, but also an efficient technical means recognized by the petroleum industry.
