夹杂物对油井管钢氢致开裂腐蚀的影响
Influence of Inclusions on Hydrogen Induced Cracking of Oil Well Pipe Steel
摘 要
对油井管钢进行了pH 2.0溶液浸泡的氢致开裂(HIC)试验。考察了油井管钢的抗HIC性能, 分析了不同种类夹杂物对钢板HIC性能的影响。结果表明, 在强酸性腐蚀环境中, 夹杂物越多, 钢对HIC越敏感。诱发油井管钢氢致开裂的夹杂物主要为MnS夹杂物、Al2O3夹杂物和硅铝酸盐复合夹杂物, 其中长条状MnS夹杂物危害最大。夹杂物诱发裂纹的初期形貌为夹杂周围出现空洞, 空洞的扩展成为氢致裂纹。

Abstract
Hydrogen induced cracking(HIC) tests in pH 2.0 corrosion solutions and inclusion analysis of oil well pipe steels were carried out. The mechanism of inclusion influence was discussed. The results showed that HIC sensitivity of the sample with more inclusions was the biggest in strong acidic solution. The inclusions which induced HIC were MnS inclusion, Al2O3 inclusion and SiO2-Al2O3 inclusion. Among the three kinds of inclusions, the strip-shaped MnS inclusion had the greatest harmfulness. The initial patter of HIC caused by inclusions was cavities around inclusions, and then cavities developed into cracks.
