摘要
论述了石油钻具在Ｈ２Ｓ等致氢环境中发生氢致应力腐蚀断裂的宏微观特征及影响因素，提出了预防钻具发生氢致应力腐蚀失效的措施．
Hydrogen\|induced stress corrosion is one of the main failure modes for drill stem elements. It was examply stated that the macro and micro features of hydrogen\|induced stress corrosion and factors affecting on it for drill stem elements in hydrogen\|producing environment.The measures to prevent drill stem elements from hydrogen\|induced stress corrosion have been put forward.
