Design of novel steel chemistries for the production of high performance tubular goods

石油国家管材（OCTG）是根据美国石油协会规范制造的油管，套管和钻杆应用。这些是通过淬火和回火处理达到目标强度的焊接管。深井中常用的一种牌号是API P110，用于甜环境，屈服强度为110-140 ksi，最小抗拉强度为125 ksi，最小伸长率为14%。随着油气井建设和环境的要求越来越高，对高性能P110 （HP P110）等更高强度等级的需求也在不断增加。该等级的屈服强度为125-140ksi，最小抗拉强度为135ksi。该项目的目的是与加拿大焊接管公司（WTC）合作，设计一种新的化学钢，可以在公司位于安大略省韦兰的工厂进行淬火和回火，以生产HP P110。

Oil Country Tubular Goods (OCTG) are manufactured for tubing, casing and drill pipe applications according to the American Petroleum Institute specification. These are welded tubes that attain their target strength through quench and tempering treatment. One of the common grades for general use in deep wells is API P110 which is used for sweet environment with yield strength of 110-140 ksi, minimum tensile strength of 125 ksi and minimum elongation of 14%. As oil and gas well construction and environments become more demanding, there is an increasing demand for higher strength grades such as High Performance P110 (HP P110). This grade has a yield strength 125-140ksi and a minimum tensile strength of 135ksi. The aim of this project is to work with Welded Tubes of Canada (WTC) to design a new steel chemistry that can be quenched and tempered to produced HP P110 at the company's facility in Welland, ON.
