摘要
减阻剂是一种长链结构的高分子烃类聚合物,在输油管道中注入减阻剂,可以有效提高管道输量,保障管道安全运行,降低固定投资,增加管道输送的经济效益和社会效益。论述了减阻剂在长输管线中的作用机理,分析了减阻剂的应用效果和影响减阻剂效果的主要因素,提出了管道输送过程中减阻剂的发展趋势,有助于指导管道的安全运行。
Drag reducing agent is a hydrocarbon polymer with long chain structure.Injecting the drag reducing agent into in the pipeline can effectively improve transmission capacity of the pipeline,ensure safe operation of the pipeline,reduce fixed investment,and increase economic and social benefits of the pipeline.In this paper,the mechanism of the drag reducing agent used in long-distance pipeline was discussed,application effectiveness of the drag reducing agent was analyzed as well as some factors to affect drag reduction effect,and development trend of the drag reducing agent used in the pipeline was proposed.
