摘　　要：津华原油管道一直采用冷热交替顺序方式输送冀东原油与俄罗斯原油,随着冀东原油物性逐年恶化,管道允许停输时间大幅降低,管道凝管的安全风险大幅提升。通过开展冀东原油与俄罗斯原油储罐罐内掺混、储罐外输在线掺混等试验,结果表明在一定的掺混比例与掺混温度下,可以实现冀东原油与俄罗斯原油掺混常温输送。掺混常温输送方式,不仅可以大幅降低因冷热交替顺序输送方式带来的凝管风险,大幅提升管道本质安全水平,而且具有巨大经济效益:经测算,在管道设计输量700×10^(4)t/a的条件下,每年可以节约能源消耗成本约1400×10^(4)元。研究结果可为国内外高温高凝与低温低凝原油掺混输送方式提供技术参考。(图6,表3,参20)Jinhua Crude Oil Pipeline always transports Jidong crude oil and Russian crude oil in an alternating cold-hot mode.With the deterioration of Jidong crude oil in physical properties year by year,the allowable shutdown time of the pipeline is greatly reduced,and the safety risk of pipeline solidification is greatly increased.Therefore,tests were performed for the mixing of Jidong crude oil and Russian crude oil in the storage tank and in-line mixing outside the storage tank.The results show that the mixed transportation of Jidong crude oil and Russian crude oil at normal temperature can be realized at a specific mixing ratio and temperature.In general,the mixed transportation at normal temperature can not only greatly reduce the risk of pipeline solidification caused by the alternating cold-hot transportation mode,greatly enhancing the intrinsic safety of the pipeline,but also achieve huge economic benefits.It is calculated that the energy consumption cost can be saved by about 1400×10^(4) yuan per year under the condition of designed pipeline throughput of 700×10^(4) t/a.The research results could provide technical reference for the mixed transportation of high-temperature high-pour point and lowtemperature low-pour point crude oils in China and abroad.(6 Figures,3 Tables,20 References)
