    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.

    In many oilfields, especially unconventional resource wells, traditional lifting equipment is prone to the following problems: Short lifespan: Sandy or corrosive well fluids cause rapid wear of the pump body; Frequent maintenance: Frequent well shutdowns for inspections lead to reduced production; High labor dependency: Experienced technicians are required to maintain operation. These pain points are driving more and more buyers in 2025 to seek solutions that reduce O&M costs while ensuring long-term stable operation. Table of Contents: Why choose an API tubing pump?

    For this reason, "how to efficiently and economically clean oil well pumps" has become a crucial concern for oil production plants, service companies, and even every on-site worker. Drawing on field experience and industry practices, we have compared and summarized the cleaning methods for API rod pumps and API tubing pumps.

    The production of a well often depends not only on the oil supply capacity of the oil layer itself, but also on the performance of the pump efficiency. The pump efficiency directly determines whether the unit energy consumption can be converted into more crude oil output. There are many factors that affect the API tubing pump efficiency, but from the three basic links of deep well pump operation (piston volume, crude oil entering the pump and crude oil being discharged from the pump), it can be summarized into the following three aspects.

    1. API Tubing Pump Definition and Principle: API tubing pump: The pump barrel is fixed to the lower end of the tubing, and the sucker rod drives the plunger back and forth to achieve suction and discharge. Compared to insert pumps (in which the pump barrel and plunger can be pulled and retracted as a single unit), API tubing pumps have thicker barrels, are more pressure-resistant, and more wear-resistant. However, this comes at the cost of requiring the tubing to be pulled for maintenance, making them less accessible.

    Designed in strict compliance with API 11AX standards, API tubing pumps utilize a one-piece rough barrel and precision grinding to ensure a precise fit with the plunger. They utilize high-strength construction, wear-resistant alloy materials, and modular wear parts.

    In the previous article, we talked about what is the difference between api sucker rod pump and submersible electric pump? If you want to know more about the related content, you can click the link to visit! Overview of API tubing pump: 1. Composition of oil pump: The pump barrel assembly of API tubing pump is directly connected to the lower end of the oil pipe, and the plunger goes into the pump barrel with the sucker rod. API tubing pump consists of two parts: pump barrel assembly and plunger assembly. The pump consists of a pump barrel, a fixed valve and a hollow plunger with a floating valve. 2. Working principle: During the pumping process, the plunger reciprocates up and down in the pump barrel with the movement of the sucker rod. During the upstroke, the floating valve ball on the plunger is closed, the fixed valve ball is opened, and the plunger discharges the liquid in the upper chamber into the upper oil pipe of the pump. At the same time, the liquid in the well enters the lower chamber of the pump barrel through the fixed valve under the action of the inlet pressure. During the downstroke, the fixed valve is closed, the floating valve is opened, and the liquid in the lower chamber of the pump enters the upper chamber of the pump barrel through the inner cavity of the plunger. The plunger surges up and down, and the liquid is continuously pumped to the wellhead. 3. Analysis of the reasons for API tubing pump repair: For coalbed methane wells, repair is mainly caused by eccentric wear and pump failure. Well repair requires all the pipes to be lifted out of the ground. There is a detailed description later.
