多年来,我国第一条长距离输油管线克一独管线,一直处于低效率下运行。虽经采取热洗等措施,但终未解决管线内壁结蜡的根本问题。随着油田石油产量的提高和原油加工量的增长,该管线的输油量也随之增加。原来管线低效率运行的状况,已不能满足生产的需要。为了完成任务,不得不采用加热、提高管线运行压力等措施,造成了大 Over the years, the first long-distance oil pipeline in China has been a single pipeline and has been operating at low efficiency. After taking such measures as heat-washing, the fundamental problem of waxing on the inner wall of the pipeline has not been solved yet. With the increase of oil production in the oil field and the increase of crude oil processing volume, the oil transportation volume of this pipeline also increases. The original inefficient pipeline operation, can no longer meet the needs of production. In order to complete the task, had to use heating to improve pipeline pressure and other measures, resulting in large
