API, which stands for the American Petroleum Institute, sets the standards for oil casing pipes used in drilling and production operations. API oil casing pipes mainly fall into two categories: seamless steel pipes and welded pipes. API oil casing pipes play a pivotal role in various processes involved in drilling and transporting oil and gas. They serve three primary functions:

1. Support During Drilling: Oil casing pipes provide stability to the wellbore, preventing collapses during drilling operations.

2. Well Completion: After the drilling process, these pipes support the integrity of the well, ensuring that hydrocarbons can be efficiently extracted without external interference.

3. Transport of Oil and Gas: These casing pipes facilitate the flow of extracted oil and gas to the surface and subsequent processing facilities.

The versatility of API oil casing pipes allows for their application in diverse environments, including high-sulfur gas fields (such as the Changqing Oilfield Sulige Block), ultra-deep wells (like the Tarim Oilfield Man-shen-1 Well), shale gas horizontal wells (such as the Fuling Shale Gas Field), and offshore platforms (like the South China Sea Liwan 3-1 gas field). In extreme conditions such as high-temperature, high-pressure deep-water drilling, the requirements for corrosion resistance, sealing integrity, and torsional strength become critical.
