摘　　要：西北地区某稠油交接站交接油温约83℃,稠油反常点为48℃,稠油交接后外输至另一稠油处理站掺混后输至炼厂。该稠油管线长度8.08 km、设计压力6.3 MPa,在保证管道安全输送的前提下,夏季在实际生产运行中进行稠油交接站降低交接油温试验。通过SPS仿真模拟软件,进一步论证管道在夏季地温及冬季最冷月下继续降温的可行性。通过核算,在相同出站温度条件下提高再启动压力,管道的安全停输时间将进一步延长;夏季交接油温可由当前83℃降低至78℃,该稠油交接站实施外输原油降温运行后总能耗将降低,半年可节省费用约6.85万元;冬季最冷月出站油温在80℃对应的安全停输时间仅为6 h,因此冬季最冷月该稠油站需维持交接油温80℃以上,不再进行降温。The oil temperature at a heavy oil transfer station in the northwest region is about 83℃,and the abnormal point of heavy oil is 48℃.After the transfer of heavy oil,it is transported to another heavy oil treatment station for mixing and then transported to the refinery.The heavy oil pipeline has a length of 8.08 km and a design pressure of 6.3 MPa.Under the premise of ensuring safe transportation of the pipeline,a heavy oil transfer station temperature reduction test is conducted during actual production and operation in summer.The feasibility of the pipeline continuing to cool down under summer ground temperature and the coldest month of winter is further demonstrated through SPS simulation software.By calculation,increasing the restart pressure under the same exit temperature conditions will further prolong the safe shutdown time of the pipeline.The summer handover oil temperature can be reduced from the current 83℃ to 78℃.After implementing the cooling operation of the exported crude oil at this heavy oil handover station,the total energy consumption will be reduced,which can save about 68500 yuan/half year in costs.The safe shutdown time corresponding to an oil temperature of 80℃ during the coldest month of winter is only 6 hours.Therefore,in the coldest month of winter,the heavy oil station needs to maintain a handover oil temperature of over 80℃and no further cooling is required.
