摘　　要：热油管道在输送原油过程中,由于输油量的变化,必然导致输油方式的改变。当热油管道的输量不能满足最小输量时,应采用间歇输送工艺来解决。在分析热油管道工艺输送过程中目标函数和约束条件的基础上,给出了埋地热油管道间歇输送的数学模型,并对间歇输送方案优化模型进行简化及求解。对间歇输送与常规输送方案能耗费用进行理论分析,又以铁大线为例,对这2种输送方案的能耗费用进行对比分析。结果表明,间歇输送的动力费用比常规输送的动力费用减少9.36%,间歇输送的总费用比常规输送的总费用减少4.47%。Intermittent transportation technique is adopted when the volume does not reach the minimum in the process of hot oil transportation. In this paper, a mathematical model is made and simplified of buried hot oil pipeline transportation with the solutions given, based on the analysis of objective function and constraint conditions of the process. A contrast analysis of energy costs is conducted between intermittent transportation and regular transportation of Tieling-Dalian pipeline. The result shows that the power cost of intermittent transportation is 9.36% lower than that of regular transportation, with a drop of 4.47% in total cost.
