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.

Table of Contents: This article will provide a comprehensive understanding of the definition of an insert rod pump, a comparison between an insert rod pump and a progressive cavity pump, its classification, the impact of different pump hole sizes, and how to install a pump. By leveraging our company's strengths in this field, we'll help you quickly make a selection decision.

Today, Dongsheng will explain which pump is best for pumping crude oil. Please follow us for a closer look. Because crude oil contains a high amount of gas, using a conventional pump can cause cavitation. This is undesirable. Therefore, a pump that can pump crude oil without cavitation is required. So, which pumps are safe from cavitation when pumping crude oil? There are many types of pumps, including insert rod pumps, pneumatic crude oil pumps, cam rotor crude oil pumps, gas-liquid mixing self-priming crude oil pumps, gear crude oil pumps, and more. To help you understand which pumps are best for pumping crude oil, Dongsheng will use the insert rod pump as a specific example.

In the field of oilfield development, choosing the right lifting equipment is very important to maintain stable oil well production and improve recovery. In recent years, insert rod pump, as an efficient and adaptable mechanical oil production equipment, has shown significant advantages under specific reservoir conditions. Its application scenarios are receiving widespread attention and practical testing from Tieling Dongsheng Petroleum Co., Ltd. and other companies in the industry.

The rod pump is the core equipment for mechanical lifting in petroleum mines. The plunger is driven by the sucker rod to efficiently extract the crude oil from the bottom of the well to the ground, which directly determines the production capacity and recovery rate of the oil well. The rod pump has a simple structure, sand resistance and wear resistance (especially suitable for inclined wells/low-yield wells), which can significantly reduce maintenance costs by more than 40%. It is the key support to extend the life of old wells and ensure stable production.
