在油气田勘探开发、炼制以及加工过程中,广泛存在H2S的腐蚀问题。硫化氢的存在会使钢材的屈服强度大大降低,最终产生应力腐蚀破坏。随着高含硫油气田的深入勘探开发,如何优选出能够适用于在高含硫环境下的高强钢,是目前亟待解决的问题。本文针对这一现状,详细介绍了H2S腐蚀机制以及H2S腐蚀的影响因素,归纳出在H2S腐蚀下高强钢的选材原则,并优选得到了三种具有耐硫化氢腐蚀的高强钢:与油田常使用的35CrMo钢比较,30CrMoVTiAI,00Cr13NiSMo和2205兼有更高的强度和耐硫化氢腐蚀性。此外,该文在此基础上对未来油气田抗H:S腐蚀的研究提出了几点建议。
在油氣田勘探開髮、煉製以及加工過程中,廣汎存在H2S的腐蝕問題。硫化氫的存在會使鋼材的屈服彊度大大降低,最終產生應力腐蝕破壞。隨著高含硫油氣田的深入勘探開髮,如何優選齣能夠適用于在高含硫環境下的高彊鋼,是目前亟待解決的問題。本文針對這一現狀,詳細介紹瞭H2S腐蝕機製以及H2S腐蝕的影響因素,歸納齣在H2S腐蝕下高彊鋼的選材原則,併優選得到瞭三種具有耐硫化氫腐蝕的高彊鋼:與油田常使用的35CrMo鋼比較,30CrMoVTiAI,00Cr13NiSMo和2205兼有更高的彊度和耐硫化氫腐蝕性。此外,該文在此基礎上對未來油氣田抗H:S腐蝕的研究提齣瞭幾點建議。

The H2 S corrosion is widely seen in oil & gas development, petroleum refining and processing. The presence of H2 S will greatly reduce the fatigue strength of steels, leading to stress corrosion failure. With the development of sulfur oil and gas fields, the selection of an appropriate high - strength steel for high - sulfur service is an urgent problem needed to be solved. The corrosion mechanisms and corrosion impact factors of H2 S are described in details, the material selection principles of high - strength steels for H2S environment are summarized and three high - strength steels are selected, i.e. 30CrMoVTiA1, 00Cr13Ni5Mo and 2205 whose strength and resistance to H2S corrosion are much higher than those of 35CrMo steel commonly used in oil field. The recommendations on R & D of H2S corrosion in oil fields are proposed.
