摘要:

采用OLGA软件建立了某油气混输管道几何模型,研究了管道停输和再启动过程中的瞬态流动规律。首先,分析了管道稳态运行时沿线温度、压力和持液率的分布特点,确定了沿线温度最小值所处位置及压力最大值所处位置,分析了环境温度和停输时间对运行参数的影响,确定了可保证温度最低点处原油温度高于其凝点的安全停输时间。在实际运行过程中,停输时间不应超过安全停输时间,否则容易出现管道凝管、启动压力过大等问题,威胁管道的安全运行。

关键词: 油气混输管道, 停输再启动, 持液率, 温降, 数值模拟

Abstract:

The geometric model of a certain oil and gas mixed transportation pipeline was established with OLGA software, and the transient flow law during the pipeline shutdown and restart process was studied. First, the distribution characteristics of temperature, pressure and liquid holdup along the pipeline during steady state operation were analyzed, and the location of the minimum temperature and the location of the maximum pressure along the pipeline were determined. The influence of environmental temperature and shutdown time on operating parameters were analyzed. The safe shutdown time when the minimum temperature temperature is higher than its freezing point was determined. In the actual operation process, the shutdown time should not exceed the safe shutdown time, otherwise problems such as pipeline condensation and excessive starting pressure will easily occur, which threaten the safety of the pipeline.

Key words: Oil and gas mixed transportation pipeline, Shutdown and restart, Liquid holdup rate, Temperature drop, Numerical simulation
