酸性油气井用油套管选材与评价方法

Selection and evaluation methods of casing and tubing materials for sour environments

介绍了相关国际标准对包括低合金抗硫管、马氏体不锈钢、镍基合金在内的酸性油气田用油套管钢使用极限和评价方法的相关规定,同时也介绍了宝钢在模拟油气田实际工况条件下各类油套管钢使用极限方面的研究进展和使用经验,并对相关标准的模糊之处进行了解读和补充。

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 inclu ding low alloy steel, martensite stainless steel and nickel based alloys. Research progress and experi- ence of the application limit of above materials in Baosteel were briefly introduced, and ambiguities of the related standards were analyzed and supplemented.
