摘要:
针对海上某油田油井管腐蚀穿孔失效现象,通过现场井况调研、材质评价、腐蚀形貌宏观观察、扫描电镜微观观察及能谱分析,结合室内腐蚀模拟试验及激光扫描共聚焦显微镜( LSCM)测量技术对穿孔原因进行了综合分析。结果表明,现场井况含有CO2和H2S,地层轻微出砂,失效管材的化学成分、金相组织和力学性能均符合标准要求,穿孔处腐蚀形貌具有流体冲刷特征,腐蚀产物主要包含C,O,S,Fe这4种元素,系CO2和H2S腐蚀产物,流速为3 m/s的腐蚀模拟试验诱发了局部腐蚀,导致管材穿孔失效。
Abstract:
For the corrosion perforation failure of oil country tubular goods in an offshore oil field, the overall failure cause was studied by the operation history analysis, material evaluation, macro analysis, SEM micro analysis, energy spectrum( EDS)analysis, corrosion simulation test of autoclave, laser scanning confocal microscope(LSCM)measurement technology. The analysis results show that the corrosive gas CO2 and H2S was detected and the formation output had a small amount of sand in the well condition. The chemical composition, metallographic structure and mechanical properties of the perforation pipe meet the requirements of product standard. The corrosion morphology of the perforation was characterized by fluid erosion. The corrosion products mainly include C, O, S and Fe elements, which were CO2 and H2S corrosion products. The corrosion simulation test with a velocity of 3 m/s induced local corrosion. Perforation failure is a synergistic effect of corrosion and erosion.
