In order to solve the problem of condensating tube of An Yong oil line, the author made this study.In fact, the subject is also a complex technical problem of drag reduction, pour point reduction, anti-wear and lubrication on long-distance crude oil pipeline, researching it is very difficult. An Yong oil line is the most complicated pipe at home and abroad. From the "3 • 14" condensating tube accident in 2009, the problem of An Yong oil pipeline in the snow and the rainy season safely operating is the point that Pipeline Transport Company and Yan Chang Oil Group of Shaanxi focus and the technical problems which they will look forward to being solved. The paper uses testing method and screening method. To take only Zhongshanchuan - Jingjiaping segment of An Yong oil pipeline as an example in this article.By laboratory and field experiment the solidifying point of crude oil heated and added depressant of Zhongshanchuan-Jingjiaping segment of An Yong oil pipeline evenly falls 10℃ above,in addition, the results show that effect of BEM-W decoagulant is the best among three depressants-BEM-W, GY-3 and EVA ,which can essentially solve safely operating problem of An Yong oil pipeline being low throughput with wax to ensure that the pipeline does not condensate tube. Therefore, the research of this topic is very meaningful and necessary.
