The Role of the Pup Joint in the Oil Field


pup joint


The pup joint refers to a pipe connection component with a shorter outer dimension, which can connect pipes with defects or different sizes at both ends. Its internal structure is usually an elastic gasket or a locking device, which realizes the tight sealing and safe operation of the connection part. The pup joint is a kind of octg pipe, which is widely used in the fields of oil, chemical industry, metallurgy, machinery, construction, etc.


The role of the pup joint in the oil field is mainly reflected in improving drilling efficiency, preventing blockage, and enhancing the stability of the connection. ‌


Improving drilling efficiency


‌By applying for a patent for a downhole low pulse pup joint, the friction resistance during drilling can be effectively reduced and the mechanical drilling speed can be increased. ‌The design of this pup joint includes a planetary valve and a central gear valve. Through a specific structure and gear configuration, the excitation frequency of the hydraulic oscillator is reduced, thereby improving the friction and drag reduction effect. ‌


Preventing blockage


‌The pup joint for valve connection can prevent the accumulation of impurities carried by the fluid in the pup joint and prevent the pup joint from clogging. ‌This pup joint is equipped with an oil inlet valve and an oil outlet valve in the pipe body, both of which are one-way valves. The elastic member pushes the valve core to seal and press it against the valve seat to form a flow channel. ‌This design is suitable for any gathering and transportation pipeline, and can effectively prevent blockage regardless of the pressure. ‌


Enhance the stability of the connection 


‌The variable diameter oil pipe pup joint solves the problem of poor connection stability of the variable diameter oil pipe pup joint in the prior art by providing a variable diameter oil pipe pup joint with good connection stability and a filter cartridge that is easy to disassemble and replace. ‌This pup joint has a novel structure and strong practicality, and can effectively solve the problem of general stability when connecting oil pipes of different diameters. ‌


Connection tool 


‌The pup joint is a drilling tool connection tool, which is commonly used to connect drill collars and drill collars, drill collars and drill bits, drill collars and drill pipes, and square drill pipes and drill pipes. It is also used to connect coring tools, salvage tools, etc. .


Bearing load


The pup joint is produced by forging method, with high plasticity, toughness and other mechanical properties, can withstand large impact force, the material meets ASTM and AISI standards, and is widely used in oilfield drilling.


Sealing performance


The pup joint has multiple sealing designs and extremely high processing accuracy to ensure the sealing performance of the entire pipeline, which is crucial to prevent oil and gas leakage.


Convenient disassembly


The use of the pup joint provides convenient and quick disassembly, firm and reliable connection, which is very important for equipment maintenance and replacement in oilfield operations.


Oil pipe connection


The oil pipe pup joint is a mechanical component for oil pipe connection in oil development. It is mainly used for oil pipe connection, and plays the role of connecting oil pipes, bearing tension, lifting oil pipes, and sealing oil pipe threads.


Preventing property loss


In the process of oil production, the use of oil pipe pup joints can avoid property losses caused by production problems. Even if the pup joint itself is small in size, it plays a key role in oil production.


Special Function Design


Some pup joints are designed with special functions, such as axial spiral protrusions on the inner wall, which can change the flow direction of the fluid, increase turbulence, and reduce clogging, which is particularly useful when conveying viscous fluids or fluids containing solid particles.


Summary


Pup joints play an important role in many aspects of oil extraction and oil and gas well operations, from connecting tools to ensuring operational safety and efficiency.

These patents and applications demonstrate the important role of pup joints in the oil field, from improving drilling efficiency to preventing pipeline blockages, to enhancing the stability of connections, they are all indispensable technical solutions in the process of oil development. ‌‌
