通过金相显微镜和电子探针分析了油井监测挂环的表面腐蚀形貌 ,比较了加药井与未加药井产出液中Fe总量的变化 ,结果表明油井主要为晶界腐蚀和湍流腐蚀 ,缓蚀剂的加入明显降低了油管的腐蚀速率
The surface corrosion morphology of the hanging ring was analyzed by metallographic microscope and electron probe. The changes of the total amount of Fe in the production fluid between the dosing wells and the unadulterated wells were compared. The results show that the oil wells are mainly grain boundary corrosion and turbulence Corrosion, inhibitor addition significantly reduces the corrosion rate of tubing
