In order to find out the fracture reasons, this paper combined the downhole tubing service working conditions to test and analyze the pipeline rupture in terms of chemical composition, mechanical properties, and microstructure morphology, and analyzed the energy spectrum characteristic of the corrosion products in the fracture site. It is recognized that the well tubing corrosion is the main reason of the fault. Through the analysis of two kinds of typical corrosion characteristics of the tubing sidetrack, it is recognized that the corrosion and pitting mechanism of the tubing wall is mainly a typical CO₂ electrochemical corrosion, and that for the side wall of the groove-like distribution of corrosion and pitting, the corrosion mechanism is electrochemical corrosion and crevice corrosion in the condition of the acid with low pH. Targeted prevention measures are also proposed for pipeline corrosion perforation on typical corrosion issues., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null,

articleAbstract=塔河油田某稠油区高含CO₂及H₂S，某侧钻井在井下P110S 油管发生典型的断裂失效。为查明油管断裂原因，结合油管服役的井下工况条件，对断裂油管的化学成分、力学性能、金相组织、微观形貌进行测试及分析，对油管断裂部位的腐蚀产物进行了能谱分析。通过对断裂油管进行详细观测及试验分析，认为腐蚀是导致该井油管断裂的主要原因。通过对该侧钻井油管二种典型腐蚀特征的分析可知油管内壁以点状腐蚀为主，腐蚀机理为典型的CO₂电化学腐蚀；外壁主要为一侧分布的沟槽状腐蚀及坑蚀，腐蚀机理为低pH 值酸液条件下的电化学腐蚀及缝隙腐蚀。针对上述典型腐蚀问题，提出了针对性预防油管腐蚀穿孔的措施。, correspAuthors=null, authorNote=张志宏，高级工程师，研究方向为采油气工程、油气田腐蚀与防护，电子信箱：wtozzh@163.com,
