摘要
通过化学成分分析、力学性能测试、显微组织分析等手段对某断裂失效的S135钻杆进行了材质理化检验;采用SEM和EDS分别对断口形貌及表面腐蚀产物成分进行了分析。结果表明:该钻杆的材料性能符合API Spec SD规范要求,钻杆断裂的主要原因是硫化氢应力腐蚀开裂,并伴有一定程度的二氧化碳腐蚀。
Material property of S135 drill pine were tested by means of chemical compositions analysis, mechanical property test and metallographic examination. Fracture suface morphology and corrosion production composition were analyzed by SEM and EDS respectively. The results show that the material properties accorded to the requirement of API SPEC 5D standard and the main reason of cracking was sulfide stress corrosion cracking （SSCC） accompanied by CO2 corrosion
