本文介绍一种油井酸化缓蚀剂的实验室测试和现场观测用的腐蚀测试仪,适用于油井钢管的腐蚀测试,具有快速、轻便,便于自制等优点。前几年我们曾用电化学方法(包括极化曲线法和极化电阻法),在浓盐酸及其添加缓蚀剂的体系中,测量了45~#钢的腐蚀速率。与失重法数据相比,表明电化学方法对该体系是适用的。由于电化学法,尤其是极化电阻法,不仅快速、简便,而且对腐蚀体系本身干扰很小。因此,近年来在工业监控、腐蚀速率测
This paper introduces a corrosion test oil well acid corrosion inhibitor for laboratory and field observation of the corrosion tester for corrosion testing of oil wells, with fast, lightweight, easy to self-made and so on. A few years ago we used electrochemical methods (including polarization curve method and polarization resistance method), in the concentrated hydrochloric acid and its corrosion inhibitor added system, the corrosion rate of 45 ~ # steel was measured. Compared with the weight loss method data, it shows that the electrochemical method is suitable for this system. Due to the electrochemical method, especially the polarization resistance method, it is not only fast and easy, but also has little interference with the corrosion system itself. Therefore, in recent years in industrial monitoring, corrosion rate measurement
