西部油田某井油管穿孔原因分析

Corrosion Failure Analysis on Tubing in a Well of Tarim Oil Field

通过宏观形貌检查、理化性能检验、扫描电镜及能谱分析等手段,分析了西部油田某井油管穿孔失效的原因。结果表明:油管在热处理时出现淬火裂纹,使得管柱内高压流体从裂缝处刺漏,最终导致管体穿孔。

Macroscopic morphology inspection, physical-chemical analysis, scanning electron microscope and energy spectrum analysis were used compositively to investigate the reasons for the failure of tubing in a well of Tarim oil field. The results indicate that the improper quenching processing leades to the occurrence of the crack, where the fluid with high pressure in the tubing can spray out with high speed, and the leakage hole is formed finally.
