In the process of oilfield development, sucker rod pump has always played a very important role. This kind of device, which drives the downhole plunger to work through the ground pumping unit, is like a loyal partner, accompanying the oil well through the middle and late stages of production attenuation. The core value of sucker rod pump lies in its reliability, durability and easy maintenance, especially suitable for the continuous production of conventional onshore oil fields. When the natural energy of the oil well is gradually exhausted, sucker rod pump becomes the key pillar to maintain stable crude oil production.

Like all artificial lift systems, API Rod Pumps are used to restore production when the reservoir's natural driving energy is insufficient to bring oil and gas to the surface. Operators are now applying this proven technology to unconventional resources that have only recently become economically and technically viable.

I. Overview of the Inclined Well Sucker Rod Pump: During oilfield production, due to formation structure and specific conditions, oil well pumps operate in wells with a certain inclination. Using conventional pumps can cause valve closure lag, resulting in lower pump efficiency and increased production costs. To address this issue, we developed the Inclined Well Sucker Rod Pump, which addresses the issue of valve ball closure lag and improves pump efficiency.

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.

In the previous article, we discussed the main causes of sucker rod pump failure and how to diagnose pumping well failures. This article will detail common troubleshooting methods for pumping wells and the steps for analyzing abnormal wells. Without further ado, let's take a look.

(1) Common forms of corrosion of Sucker rod pumps include brittle corrosion, acid corrosion, fracture corrosion, electrochemical corrosion, pitting corrosion and abrasion corrosion.

Challenges of Inclined Well Pumping Application Scenarios of Inclined Well Sucker Rod Pumps Comparison of Common Artificial Lift Methods Structure and Features of Inclined Well Sucker Rod Pumps Pump Types and Selection How to Choose the Right Inclined Well Sucker Rod Pump Conclusion and Recommendations In oil production, rod pumping remains the most common method of artificial lift. However, traditional vertical well pumping methods face many challenges in inclined well environments. Inclined well sucker rod pumps are designed to address these challenges.

API type tubing pumps and API type rod pump​s are two common types of mechanical oil production equipment. Due to their structural differences, their application performance in different well conditions varies. Choosing the right pump based on well depth, production rate, and ease of maintenance has always been a core concern for oilfield engineers and production units. This article will provide an in-depth analysis of the structural characteristics and application scenarios of API type tubing pumps and API type rod pumps, helping you quickly compare their advantages and limitations.

The main difference between tubing pumps and insert rod pumps is that tubing pumps have a simple structure and low cost. The diameter of the pump that can be inserted under the same oil pipe diameter is larger than that of insert rod pumps, so the displacement is large. However, when inspecting the pump, the oil pipe must be started, and the workload of repairing the well is large. It is suitable for oil wells with small depth and high production. Insert rod pumps are convenient for pump inspection, but have a complex structure and high manufacturing cost. The diameter of the pump that can be inserted under the same oil pipe diameter is smaller than that of tubing pumps. Insert rod pumps are suitable for oil wells with large depth and low production.
