某井S135钢级钻杆腐蚀失效原因
Reasons for Corrosion Failure of S135 Steel Grade Drill Pipe in a Certain Well
摘 要
某井S135钢级钻杆在钻进约2 395 m时发生腐蚀失效。采用宏观形貌、断口形貌观察，显微组织分析，化学成分、硬度、腐蚀产物成分测试对其失效原因进行了分析。结果表明：该钻杆的失效方式为腐蚀疲劳失效，钻杆内壁的氧含量偏高及内壁加厚过渡带区域存在应力集中，导致加厚过渡带区域发生严重点蚀，点蚀坑底部萌生疲劳裂纹并扩展，最终钻杆失效；建议使用内壁带防腐涂层的钻杆，并在钻井液中添加缓蚀剂，降低溶解氧对内壁的腐蚀作用，同时优化井深结构，减缓内壁加厚过渡带区域的应力集中。

Abstract
The S135 steel grade drill pipe of a certain well suffered corrosion failure when the drilling distance was about 2 395 m. The fracture reason was analyzed by macromorphology and fracture morphology observation, microstructure analysis, and chemical composition, hardness, and corrosion product composition tests. The results show that the failure mode of the drill pipe was corrosion fatigue failure. The inner wall of the drill pipe had high oxygen content and stress concentration in the thickened transition zone of inner wall, resulting in severe pitting corrosion in the thickened transition zone. Fatigue cracks were initiated in the bottom of the pits and propagated, fainally leading to the failure of the drill pipe. It was recommended to use the drill pipe with anticorrosive coating of inner wall, add corrosion inhibitor to the drilling fluid to reduce the corrosion effect of dissolved oxygen on the inner wall, and optimize the well depth structure to reduce stress concentration.
