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!

Application requirements of sucker rod pump: In the process of working of sucker rod pump, in order to ensure the long-term production capacity of oil fields, you can refer to the following contents: (1) the material strength of the suction valve and plunger of sucker rod pump must meet the actual use requirements, especially the pump barrel structure that bears the most pressure, which must have sufficient strength, hardness and sealing at the same time, and its overall shape will not deform when subjected to high pressure. (2) sucker rod pump needs to work underground for a long time, and in this extremely closed working environment, the equipment itself needs to have extremely high stability and reliability, and must have a long service life. (3) various valves and plungers need to meet the corresponding process requirements in terms of quality and material strength, and have high corrosion resistance, and pay attention to the impact of the working process of sucker rod pump on valves and plungers. (4) pay attention to daily maintenance procedures, and solve various problems faced by sucker rod pump in a preventive manner. Below, we will conduct a specific analysis of several common problems, hoping to help friends who encounter such problems. Let's read on!

Layered oil production: Background. In view of the current situation that the oil well joint production cannot meet the production needs due to the prominent contradiction between multiple layers and layers, the layer-stuck method is generally adopted for production. The main layer-stuck pipe string structure is as follows: Control layer-production layer. Production layer-control layer. Production layer-control layer-production layer. Through the application of various layer-stuck pipe strings, the problem of inter-layer interference is effectively solved, but the full play of the production capacity of each layer of the oil well is limited. At present, there is an urgent need for a layered co-production technology that can effectively mobilize each contributing oil layer and avoid inter-layer interference, fully tap the production capacity of the oil well, increase the production of the oil well, and improve the development time.

1. Description of the problem： When the pumping well is abnormal during the production process, it is necessary to perform maintenance inspection of the deep well oil well pump. Due to scaling, the piston of some operating oil wells is stuck in the pump barrel of the deep well oil well pump, which makes it difficult to lift it during the well repair operation. At this time, it is necessary to reverse the rod pipe. The reverse rod is reversed by 2-3 operators using pipe pliers at the wellhead. The operation is very dangerous and there have been many injuries in the past. Through on-site observation and research, the sucker rod reverser is made.

API subsurface rod pump, polished rod and coupling are components of rod pumping equipment, which transmit the power of the pumping unit to the downhole pump. The API subsurface rod pump column is made up of dozens or hundreds of API subsurface rod pumps connected by couplings. During the oil production process, the API subsurface rod pump column is subjected to asymmetric cyclic loads, and the working medium is well fluid (crude oil and mineral water), and the well fluid of many pumping wells contains corrosive media. Therefore, the main failure form of API rod pump is fatigue fracture or corrosion fatigue fracture. The breakage accident of API subsurface rod pump will seriously affect the crude oil production, increase the cost of well repair, and increase the cost of crude oil.

​Today, we will take you to learn more about the structural composition, coupling types and precision manufacturing process behind the API standard sucker rod pump. How is the high-quality API standard sucker rod pump manufactured? Let's take a look at it together! Let's first take a brief look at the structure and grade classification of the API standard sucker rod pump: The API standard sucker rod pump is connected by a coupling to form a complete API standard sucker rod pump column. The top is connected to the pumping unit through a bare rod, and the bottom is connected to the plunger of the pumping pump, which accurately transmits the reciprocating motion of the ground pumping unit to the downhole pump body.
