摘要: 地形起伏管道在输送湿气过程中容易出现管道积液的现象，继而影响到管道运行的安全性。积液的产生与多种因素有关，为了研究KL输气管道积液敏感性，利用多相流模拟软件OLGA建立输气管道积液模型，模拟计算分析了不同影响因素对管内总积液量和沿程持液率的影响规律。结果表明，起点输量对积液的影响最大，烃露点温度的影响次之，末端压力和埋深温度影响甚微；将输量控制在合理的范围内(2500 × 104~3000 × 104 m3/d)，有利于改善管内积液状况，保障管道平稳高效运行。
Abstract: Liquid accumulation in gas pipelines with terrain variations during the transportation of moist gas can affect the safety of pipeline operation. The occurrence of liquid accumulation is related to various factors. In order to study the sensitivity of liquid accumulation in the KL gas pipeline, a liquid accumulation model was established using the multiphase flow simulation software OLGA. The effects of different influencing factors on the total liquid accumulation and liquid holdup along the pipeline were simulated and analyzed. The results indicate that the initial flow rate has the greatest influence on liquid accumulation, followed by the hydrocarbon dew point temperature, while the effects of the terminal pressure and burial depth temperature are minimal. Controlling the flow rate within a reasonable range (2500 × 104~3000 × 104 m3/d) is beneficial for improving the liquid accumulation condition inside the pipeline and ensuring smooth and efficient pipeline operation.
