摘要如今，管道运输已经成为国家发展必不可少的运输方式之一。相对于其他的运输方式，管道运输有价格低、简单、稳定的特点。这些年输油管道的不断完善，它在国民经济中扮演着重要的角色。但是，输油管道也有一定的弊端。由于人为、自然灾害、管道自身等各种的因素，导致管道破损的现象经常出现。不仅造成了石油资源的严重浪费，同时也给人们的生活带来了很大的困扰，还有就是给我国国民经济带来了损失。因此，找到和完善有效的输油管道破损检测装置是我们现在迫切要解决重要课题内容。76848
本文依据超声波方法，基于相关分析的理论对输油管道检测。实践证明此方法可以大大的提高破损检测的精度，是一种简单实用的方法。同时讨论用相关分析进行输油管道的破损检测的优缺点，为进一步研究输油管道检测提供了参考依据。

Research and Development of Oil Pipeline Damage Detection Device based on Correlation Analysis
Abstract Nowadays, pipeline transportation has become one of the most important means of transportation in our country。 Compared with other modes of transportation, pipeline transportation has the characteristics of convenient, economical and safe。 With the rapid development of the oil pipeline, and constantly improve, it plays an important role in the development of China's economy。However, there are some disadvantages of the oil pipeline。Due to man-made, natural disasters, the pipeline itself and other reasons, resulting in leakage of oil pipeline leakage accident occurred frequently。Not only caused a serious waste of oil resources, but also to people's life has brought a lot of trouble, and that is to bring the loss of our national economy。 Therefore, it has become an urgent problem to find and improve the effective pipeline damage detection device。
This paper, on the basis of ultrasonic method, based on the theory of correlation analysis of pipeline detection。 It is proved by practice that this method can greatly improve the accuracy of damage detection, is a simple and practical method。 At the same time, we discuss using correlation analysis of pipeline damage detection of advantages and disadvantages, and provide a reference for further study on oil pipeline detection

1。1 管道运输的发展状况
输油管道是最现代，最实惠的运输方式之一，在运输液、气体等方面它体现出独有的特点。当油气物料作为被运输时，被输送的物料遗失泄露少、过程安全而且污染低，这些优点使得管道运输成为石油运输的最经济、安全的选择。世界上第一条输油管道是在1865年由美国修建的，从此管道运输开始有了发展。论文网 相关分析的理论输油管道破损检测装置的研发:http://www.youerw.com/zidonghua/lunwen_88216.html
