摘　　要：文章主要介绍了石油套管抗硫化氢应力腐蚀性能的影响因素和控制要点。为满足高强度抗硫化氢腐蚀套管的使用要求,选用Cr、Mo、Ti为主要抗腐蚀合金元素,严格控制S、P的含量,通过微合金元素合理优化,生产出了具有自主知识产权的抗硫化氢石油套管,0℃冲击吸收功达到100 J以上,使套管在具有高强度的同时也具有很高的韧性,强韧性搭配合理,产品具有良好的抗硫化氢腐蚀性能。In this paper,it is mainly introduced the influencing factors and control main points of the resistance to hydrogen sulfide stress corrosion for oil casing.In order to meet the usage requirements of high strength oil casing resistant to hydrogen sulfide corrosion,the oil casing resistant to hydrogen sulfide with independent intelligent property rights is manufactured through selecting Cr,Mo,and Ti as the main corrosion resistant alloy elements,strictly controlling contents of S and P as well as reasonably optimizing microalloy elements.Its impact absorbing energy at 0℃reaches over 100 J,so it is with both high strength and toughness as well as they match reasonably so that it is with good resistance to hydrogen sulfide corrosion.
