Faced with multiple well conditions such as shale oil, high corrosion, and high sand content, rod pumps are still the equipment in artificial lift. Which types of pumps perform better? Which ones are suitable for different user needs? What are the advantages and limitations of plunger lift solutions?

Our Tieling Dongsheng Petroleum Machinery Co., Ltd. it is a company specializing in the production and manufacture of petroleum extraction machinery and parts. Our API tubing pump is produced in Liaoning, China, with an annual supply capacity of 20,000 pieces and a delivery time of only 8-10 weeks. It can provide stable and reliable solutions for oilfield customers around the world.

Our thermal recovery sucker rod pump is specially designed for the field of thermal recovery in oil fields and is designed to solve the problem of steam recovery in heavy oil extraction. Our thermal recovery sucker rod pump is produced in Tieling Dongsheng Petroleum Machinery Co., Ltd. , our annual supply capacity reaches 20,000 pieces, and we promise a standard delivery cycle of 8-10 weeks to meet the needs of global oilfield projects.

Ⅰ.The use of rod pumps to pump oil is the core method of oilfield mechanical oil recovery： In oilfield development, when the oil well cannot be self-injected due to insufficient formation energy, thick crude oil, etc., or the output is too low, it is necessary to use mechanical energy to recover oil. At present, the main mechanical oil recovery methods we use include gas lift oil recovery and deep well oil sucker rod pump oil recovery, and rod pump pumping is one of the important types of deep well oil sucker rod pump oil recovery. With the advantages of simple structure and easy maintenance, it is most widely used in oil fields around the world, especially in shallow and medium-sized oil wells.

The air lock problem in heavy oil mining is being gradually solved by our company. We Tieling Dongsheng Petroleum Machinery Co., Ltd. with the design of this mechanical valve, the forced valve rod pump has achieved a breakthrough in reducing the air lock rate by 90% in oil fields such as Liaohe and Daqing. Today we will pass some key questions and answers to uncover the innovative core of this domestic technology.

Ⅰ. The structure of deep well oil sucker rod pump： Pumping rod pump is also called deep well rod pump. Our deep well oil sucker rod pump is a special equipment for mechanical oil recovery with rod pump.Under the pump, it is at a certain depth below the moving liquid level in the well shaft, and relies on the sucker rod to transmit the power of the sucker to extract the crude oil from the ground. Deep well oil sucker rod pump is divided into combined pumps and whole cylinder pumps according to whether there is a bushing or not. The working cylinder of the combined deep well oil sucker rod pump has several bushings, and it is pressed by the upper and lower compression joints; the working cylinder of the whole pump is a seamless steel pipe without a bushing inside. Deep well oil sucker rod pump is divided into two types: tubular pump and rod pump according to its installation method and structure in the well.

In the process of extracting oil, we will encounter some problems of aging or damage to equipment. At this time, we need to maintain and overhaul the equipment in a timely manner, and even replace the necessary parts and components. We all know that when mining oil fields, well workers sometimes can't see the underground environment so clearly. Petroleum may also have chemical effects on iron machinery. In the long run, it is inevitable that mechanical parts will rust, so at this time we need to replace the mechanical parts.

We Dongsheng Petroleum Machinery Co., Ltd.Launched a professional protection plan for the global transportation of brass pump barrels, through standardized packaging, environmental control and full process monitoring, in order to ensure zero damage to the brass pump barrels from the Liaoning factory to the international oilfield site.We have successfully applied this system to orders from more than 20 countries such as the United States and Canada, and the transportation loss rate has decreased significantly, which has become a key pillar to protect the interests of customers.

In the underground world of oil extraction, API standard sucker rod pump is like a tireless "underground miner", lifting crude oil from deep strata to the surface day and night. How does this seemingly mysterious equipment work? What "special skills" does it have to cope with different extraction environments? Today, we will unveil the technical veil of API standard sucker rod pump.

In the previous article, we mentioned the problems of sucker rod pump valve cover disconnection, pump failure, and valve leakage. Combined with the years of work experience of our technicians, we give specific suggestions. Let's take a look!
