摘　　要：埋地管道运输是目前原油的主要输送方式,它的使用优点日益突出。由于埋地管道运行环境复杂,各种原因造成的管道腐蚀严重影响其使用寿命和所输油品质量,甚至造成泄漏而污染环境。通过对埋地输油管道的腐蚀特点及其影响因素进行分析,包括腐蚀的种类和相应的防护措施,指出了防腐覆盖层各有优缺点,应根据管道线路的地质条件、环境而定,提出了今后管道腐蚀的发展方向。Buried pipeline transportation of crude oil is the main transmission mode,and its use has become increasingly obvious advantages,because it operational environment is complex,a variety of reasons for pipeline corrosion that causes a serious lose of their service life and affects the quality of oil or even causes leakage pollution of the environment. Buried pipeline corrosion char- acteristics and influencing factors are analyzed, including the type and the corresponding corrosion on the protective measures, by nothing that the anti-corrosion coating has advantages and disadvantages,according to the geological conditions under which the pipe lines are laid. In light of the environment, some suggestions are brought forward for prevention of pipeline corrosion in future.
