Cause of coiled tubing fracture of a high-temperature and high-pressure gas well in a western oilfield
摘 要
某西部油田高温高压气井连续油管在下井过程中发生断裂,采用宏观观察、无损探伤、化学成分分析、力学性能试验、金相检验、扫描电镜及能谱分析等方法,分析了连续油管断裂的原因。结果表明:该连续油管在下井过程中,管壁发生结腊,连续油管受到压缩载荷,导致下井受阻,当压缩载荷超过材料屈服强度后,连续油管发生压缩变形,随后发生断裂。
Abstract
The coiled tubing of a high-temperature and high-pressure gas well in a western oilfield fractured during the downhole process. Macroscopic observation, non-destructive testing, chemical composition analysis, mechanical performance test, metallographic inspection, scanning electron microscopy and energy spectrum analysis were used to analyze the cause of coiled tubing fracture. The results showed that during the downhole process of coiled tubing, wax formation occurred on the pipe wall. The coiled tubing was subjected to a compressive load, which caused the downhole to be blocked. When the compressive load exceeded the yield strength of the material, the coiled tubing was compressed and deformed and subsequently fractured.
