减阻剂是输油管道快速的增输手段。文中列举了国外利用减阻剂实现增输的典型实例。在管道已定的情况下,管道的输量如何适应产、销外界提出的增输要求,而投放减阻剂乃是较为灵活、经济、快速的方法。同时阐明了国内管道使用减阻剂实现经济增输的可行性;随着国内减阻剂的不断开发,减阻剂必将在长输管道输油中,发挥其快速增输的作用。 Drag reducing agent is the rapid increase of oil pipeline means. The article lists some typical examples of using drag reducing agent abroad to increase output. In the case of the pipeline has been set, the pipeline output to meet the production and marketing requirements put forward by the outside world, and put DRA is a more flexible, economical and rapid way. At the same time, it clarifies the feasibility of domestic pipeline using DRA to realize economic increase. With the continuous development of domestic DRA, drag reducing agent will surely exert its role in rapid pipeline transportation in long-distance pipeline transportation.
