阿拉山口-独山子原油管道自2006年投产以来,已运行5年多,由于管道的计划检修、管线设备的老化、自然灾害或人为因素造成的事故抢修等都可能造成管道的全线停输。本文通过对阿独原油管道现有输量、不同油品物性参数和不同月份平均地温综合考虑,对需加热输送的油品安全停输时间进行计算,得出了不同倾点原油在满足热力输送月份的安全停输时间。 The Alashankou-Dushanzi crude oil pipeline has been in operation for more than five years since it was put into operation in 2006, which may result in the suspension of the pipeline due to planned maintenance of the pipeline, aging of pipeline equipment, accidental rescue caused by natural disasters or human factors. Based on the comprehensive consideration of the current output of Aduo crude oil pipeline, different oil physical parameters and the average ground temperature in different months, this paper calculates the safe shutdown time of the oil products to be heated and delivered, Month of safe shutdown time.
