| 摘 要： | 清管作业是油气管道生产过程的必要环节，对管道安全运行管理具有重要意义。对于码头卸油来说，当同一条管道收油种类发生变化时，必须清管。因此，在分析清管介质对成品油管道综合影响的基础上，建立了氮气通球清管数学模型。以天津港某码头卸油管线为例，进行计算，得出了不同时刻管内氮气量、进口压力及清管球的位置。计算结果可为实际工程设计提供一定的参考。

| Abstract: | Pigging operation is a necessary part of the oil and gas pipeline production process, and it has great significance for the pipeline safety operation management. For pier offloading, pigging must be done when the type of oil revenues is change in the same pipeline. So a mathematical model of the nitrogen through ball pigging was established on the basis of analyzing the comprehensive influence of pigging medium on the product oil pipeline. Taking Tianjin port pier offloading pipeline for example, the calculation was done. The amount of nitrogen, inlet pressure and the pigging ball position at different time in the pipeline was obtained. The calculation results can provide some basis for the actual engineering design. |
