文章探讨了东海海域富阳一井钻井施工中出现的钻杆刺漏现象 ,并对刺漏钻杆进行解剖研究 ,结合国内外钻杆刺漏的事例 ,指出腐蚀疲劳是钻杆刺漏的根本原因 ,并提出了预防钻杆腐蚀疲劳失效的合理化建议。 This paper discusses the phenomenon of drill pipe leakage in the drilling of Fuyang-I Well in the East China Sea. Anatomy of the drill pipe leakage is also analyzed. Combined with the cases of drill pipe leakage at home and abroad, it is pointed out that the corrosion fatigue is the root cause of pipe leakage , And put forward reasonable suggestions to prevent fatigue failure of drill pipe corrosion.
