PUP JOINT flow line pipe with fig 1502 union

In the process of crude oil and natural gas exploitation, oil pipes, as an important facility for oil and gas transmission after drilling, can transport crude oil and natural gas in oil and gas reservoirs to surface pipelines, which are widely used in oil and gas fields. Compared with foreign oilfields, the downhole environment of China's oilfields is more complex, and the problem of TUBING corrosion is particularly prominent in China. According to incomplete statistics, 80% of workover operations in a gas field are related to the corrosion failure of tubing. The high temperature and high pressure environment, multiphase fluid scouring, H2S, CO2 and high salinity during the service of tubing are the important reasons for tubing corrosion. The shortest occurrence time of tubing corrosion failure is less than October. Most oilfields usually have corrosion failure 1~2 years after production. Corrosion failure will not only cause damage to a large number of tubing, but also lead to tubing fracture in the well when it is serious, leading to abandonment of the well, causing huge economic losses and environmental pollution, and even threatening personal safety. Therefore, it is very important to study the causes of tubing failure, which can be used to formulate preventive measures to avoid accidents.

The pup joint are used to adjust the height of full length tubing or CASING strings, they are also used to asjust the depth of downhole tools.
