摘要
API(美国石油协会)13Cr油套管具有良好的耐CO_2腐蚀性,但随新油田的开发,要求油套管具有优良的抗H_2S、CO_2高温耐蚀性。文中分析了国内外非API 13Cr马氏体不锈钢油套管(Cr13-Ni5-Mo,Cr13-Ni5-Mo2,Cr15-Ni6-Mo2-Cu等)的发展现状,叙述了相关生产厂家油套管的化学成分、力学性能和耐蚀性。
The API 13Cr for oil tube and case has good corrosion resistance in CO_2,but with new oilfield development, it requires the steel for oil tube and case has excellent corrosion resistance in H_2S and CO_2 at elevated temperature. The development status of non-API 13Cr martensitic stainless steels for oil tube and case including Cr13-Ni5-Mo,Cr13- Ni5-Mo2,and Crl5-Ni6-Mo2-Cu at home and abroad are analyzed in this paper and the chemical composition,mechanical properties and corrosion resistance of steels for oil tube and case produced at relative steelworks are presented.
