The development and application of premium thread connection tubing and casing products from Baosteel

Premium thread connection tubing and casing products are non-API products that are used in severe oil field conditions, such as deep wells ,ultra deep wells, high pressure gas wells, horizontal wells and steam injection wells, etc. In order to meet the requirements of oilfields for premium thread connection oil country tubular goods （ OCTG）, Baosteel developed its own series of premium thread connection tubing and casing products that are protected by intellectual property rights. This study introduces the process of developing the premium thread connection tubing and casing products, their characteristics, and their actual application in oil fields. It hopes to give customers a better understanding of Premium thread connection tubing and casing products from Baosteel.
