| Abstract: |
| In this paper, the application limit and evaluation methods of casing and tubing materials used in sour oil or gas wells in related international standards were discussed, these materials including low alloy steel, martensite stainless steel and nickel based alloys. Research progress and experience of the application limit of above materials in Baosteel were briefly introduced, and ambiguities of the related standards were analyzed and supplemented. |
| Key words: casing and tubing materials application limit sour environment evaluation method |
