摘　　要：针对近海油料输转系统管线排空作业,建立了管线排空数学模型,运用MATLAB软件,计算了在不同工作压力情况下,管线总的排空时间;分析了在不同时间间隔下,管线受到的摩擦阻力和速度分布情况;运用ANSYS软件,构建了管线排空数值模型,分析了管线压力分布、速度分布以及流体轨迹分布规律,对掌握管线排空作业过程中的力学规律具有指导意义。This paper focuses on the pipeline evacuation of offshore oil transportation system. The mathematical model for pipeline evacuation was established,and the total emptying time under different working pressure was calculated by using MATLAB software. Frictional resistance and velocity distribution of the pipe under different time intervals was analyzed. The numerical simulation for the pipeline evacuation was carried out by using ANSYS software. The pressure distribution,velocity distribution and distribution law of the fluid trajectory are analyzed,which will make contribution to the analysis and control of the variation of the pipeline during the evacuation operation.
