Abstract: Drill pipe damage primarily manifests as grooves and scratches on the joint shoulder, as well as corrosion and erosion of the pipe body. This article analyzes the causes of drill pipe damage and maintenance methods during drilling operations, aiming to provide guidance for drilling operations, extend the service life of drill pipe, and prevent
Post-weld heat treatment (PWHT) of pipelines usually refers to heat treatment below the metal's phase transition point, which is also commonly referred to as stress relief. The main functions of post-weld heat treatment are to release residual stress, reduce diffusible hydrogen, and improve microstructure and properties. In addition, post-weld heat treatment (PWHT) has other functions
Currently, commonly used methods for cleaning oil pipes can be divided into two main categories: physical cleaning and chemical cleaning. These primarily include hot boiling cleaning, heating cleaning, laser cleaning, biological cleaning, ultrasonic cleaning, dry ice cleaning, and water jet cleaning. Below are several cleaning methods: Heating Cleaning The substances adhering to the surface
Large free forging equipment is a hallmark of a country's industrial development level, and the large forgings produced play a vital role in national economic construction, defense equipment, and central installations in modern cutting-edge science. As various industries gradually shift towards larger and higher-standard equipment manufacturing, the internal quality requirements for large forgings are also
Stabilizers are standard downhole tools in drilling assemblies. Complex downhole situations and accidents related to them often occur during drilling. Despite extensive analysis and improvements by researchers and manufacturers, the problems have not been completely resolved. The Graf project is located in southern Iraq, where multiple wells have experienced downhole stabilizer breakage during operations.
