摘　　要：目前原油储罐服役时间长、储装介质的腐蚀以及自然环境变化等共同作用,使得原油储罐存在不同程度的腐蚀,严重会导致穿孔。因此定期对储罐腐蚀情况进行检测评价至关重要。目前,多采用超声波壁厚检测方法了解储罐腐蚀情况,但是目前常用的检测方法存在一定的缺陷,将直接影响储罐腐蚀检测评价的准确性。文章通过研究提出了改进原油储罐超声波壁厚检测的方法,并将这一检测方法应用在了某一储罐的超声波壁厚检测中,结果证明,该方法的利用有利于更能准确地检测到储罐壁厚腐蚀减薄最严重的点,为腐蚀评价以及整改措施的提出提供更为准确的第一手评判依据。At present, the long service time of crude oil storage tank, the corrosion of storage medium and the change of natural environment make the crude oil storage tank exist different degrees of corrosion, which will lead to serious perforation. Therefore,it is very important to inspect and evaluate the corrosion of storage tanks regularly. At present, most of the ultrasonic wall thickness detection methods are used to understand the corrosion of storage tanks, but there are some defects in the commonly used inspection methods, which will directly affect the accuracy of tank corrosion detection and evaluation. This paper puts forwarda method to improve the ultrasonic wall thickness detection of crude oil storage tank, and applies this method to the ultrasonic wall thickness detection of a certain storage tank. The results show that, the use of this method is conducive to more accurate detection of the tank wall thickness corrosion thinnest or the most serious point, so as to providea more accurate first-hand evaluation basis for the corrosion evaluation and correction measures.
