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 oil extraction, tubing pump, as a mature and reliable mechanical oil production equipment, continues to provide the core driving force for stable oilfield production. Tieling Dongsheng Petroleum Co., Ltd. has been deeply engaged in the research and development and manufacturing of oil production equipment for more than ten years. Relying on structural optimization and technological innovation, its tubing pump series products have been applied on a large scale in many domestic oilfield blocks, effectively supporting the development needs of old wells to increase production and new wells to improve efficiency.

The tubing pump is an underground pumping device directly fixed to the bottom of the oil pipe. The plunger is driven by the pumping rod to reciprocate and lift the crude oil from the bottom of the well to the ground. Its simple structure and low cost are suitable for oil wells with medium and low production and stable well conditions, but the entire oil pipe needs to be removed during maintenance.

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.

Oilfield development has entered the middle and late stages, and it is a common phenomenon for formation energy attenuation to cause oil wells to lose their self-injection capacity. Artificial lift technology drives downhole equipment through external power to establish a continuous flow channel of crude oil from the reservoir to the ground, which has become a key technical means to maintain oil and gas production. Artificial lift technology is essentially a scientific supplement to subsurface energy, which can effectively overcome mining obstacles such as insufficient reservoir pressure and fluid viscous resistance.

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.

Rod pumps are usually divided into three types, namely: tube pumps, rod pumps and special pumps. Tubular pump: The pump barrel is directly connected to the bottom of the tubing, which is suitable for shallow or medium-deep wells. It has the characteristics of simple structure and easy maintenance. Rod pump: The pump body is suspended underground through a sucker rod, which is suitable for deep wells and has a strong pressure bearing capacity, but the installation and maintenance are relatively complicated. Special pumps: such as sand-proof pumps, anticorrosive pumps, etc., are designed for specific geological conditions and are used to solve problems such as sand stuck and corrosion.

Insert rod pump is a kind of mechanical equipment widely used in the field of petroleum extraction, mainly used to extract crude oil from oil wells. The design concept of insert rod pump is based on artificial lifting technology, which mechanically lifts the fluid in the formation to the ground, thereby overcoming the natural flow difficulties caused by insufficient reservoir pressure. Insert rod pump has the characteristics of simple structure, high reliability and strong adaptability, and plays an outstanding role in low-permeability reservoirs and high-water-bearing oil wells.
