- 摘要:
- 储气库注采同管设计可节省管材用量,减少投资,但部分储气库在采气时含有少量的H2S,需采用高钢级厚壁抗硫管线钢。分析了高钢级厚壁抗硫管线钢的关键技术要求,对高钢级抗硫管线钢的应用现状、存在问题及研究进展进行了统计分析,结合储气库自身特点对高钢级厚壁抗硫管线钢的应用开展了技术可行性研究,并选取2段国产X65QS厚壁管进行了试验验证。研究结果显示:通过合适的过程质量控制,X65钢级管线钢仍具有良好的抗氢致开裂(Hydrogen-induced Cracking,HIC)和硫化物应力开裂(Sulfide Stress Cracking,SSC)性能,相对而言X65QS较X65MS具有更优异的抗SSC性能;国产X65QS厚壁无缝管母材组织均匀,晶粒度和硬度控制良好,母材及环焊缝均通过了ISO 15156-2:2020《石油天然气工业——石油和天然气生产中含H2S环境使用的材料 第2部分:抗开裂碳钢、低合金钢和铸铁》标准规定的资格试验,具有优异的抗HIC和抗SSC性能。研究验证了X65QS钢级厚壁抗硫管线钢在储气库酸性工况应用具备技术可行性,可为含硫储气库的设计优化提供参考。
The design of using a single pipeline for both gas injection and production in gas storage facilities can save pipe material and reduce investment. However, some gas storage facilities contain trace amounts of hydrogen sulfide during gas production, necessitating the use of high-strength thick-walled sulfur-resistant pipeline steel. This paper analyzes the key technical requirements for high-strength thick-walled sulfur-resistant pipeline steel, reviews the current application status, existing challenges, and research progress of high-strength sour-resistant pipeline steel, and conducts a technical feasibility study on the application of such steel based on the specific characteristics of gas storage facilities. Experimental verification was performed on two segments of domestically produced X65QS thick-walled pipes. The results show that: with proper process quality control, X65 grade pipeline steel maintains excellent resistance to hydrogen-induced cracking(HIC) and sulfide stress cracking(SSC); comparatively, X65QS exhibits superior SSC and sour resistance relative to X65MS; the microstructure of domestically produced X65QS thick-walled seamless pipes is uniform, with well-controlled grain size and hardness; both the base material and circumferential welds passed the qualification tests specified in ISO 15156-2: 2020 Petroleum and natural gas industries—Materials for use in H2S cotanining environments in oil and gas production—Part 2: Cracking resistant carboon and sow alloy steels, and the use of cast irons, demonstrating excellent HIC and SSC resistance. This study confirms the technical feasibility of thick-walled X65QS grade sulfur-resistant pipeline steel for use in acidic service conditions of gas storage facilities, and provides a reference for design optimization of sour gas storage facilities.
