Fracture Failure Analysis of N80 Q Marine Casing
The 13-3/8 casing of a well was bent down and broken off in the marine development completion process.The cause for the fracture is systematically analyzed by means of chemical composition analysis, mechanical properties testing, macro and micro fracture analysis and metallographic analysis.The results indicate that, the heterogeneity of the casing material and large oxide metallurgical inclusions found in fracture place severely reduce the properties of the material, which lead to the failure of casing pipe in bad service environment.
