摘要
氢致裂纹和滞后断裂是石油管材的主要失效形式之一。论述了石油管材的氢致裂纹和氢致滞后断裂（应力腐蚀）的区别和联系，重点讨论了石油管材在H2S中产生氢致裂纹的特征和条件，以及钢中非金属夹杂物、化学成分、组织结构等对氢致裂纹的影响。同时，讨论了石油钻具氢致滞后断裂的特点；提出了预防氢致开裂和氢致应力腐蚀的若干措施。
Hydrongen－induced cracking(HIC) and stress corinsion are two main modes of tubular goods failure. The differenceand relations of them are expounded. The characteristics and occurrence conditions of lhe hyhan－induced cracks inpipelines serving in H2S containing medium are discussed in detail, and the influences of non－metallic inclusions, chemical compositions and microsmictures in the steel on HIC are analyzed. In addition, the characteristics of HIC and hydrigen－induced stress cormsion in drilling thels are descrihed, and relevant preventions are offered.
