- 摘要:
- 苏里格气田地面环境恶劣,由于地形起伏变化较大,在集输管道中极易形成段塞流,造成管路的不稳定振动。如何准确预测管道系统段塞流的形成对高效开发苏里格气田具有非常重要的意义。现采用TACITE软件对苏-10井区集气阀组管道的正常投产和通球情况下的段塞流进行预测,并采用PIPEFLO软件对其结果进行验证,结果表明:TACITE计算结果比PIPEFLO计算结果较保守。经预测,在苏-10井区由于地形变化大产生了地形段塞流,流体在流动过程中流型等流动特性发生了变化。流体经上凹肘部时会产生段塞积液,引起不稳定的振动现象,导致液体出流,流体经上凸肘部时,由于流动特性变化,段塞流可能存在或消失。在通球过程中,由于清管器的运行,使管道各点出现超高压力值,应引起注意。
Since the terrain changes rapidly in Sulige gas field,it is easy to generate terrain-induced slug flow leading to vibration in gas gathering pipelines.Therefore it is very important for the development of Sulige Gas Field to predict the slug flow and optimize the gas gathering pipelines and facilities downstream.The software TACITE was used to simulate slug flow modeling of gas gathering pipeline with valves in the phases of typical production and pigging operation at Sulige 10 Block.And the results were validated by the software PIPEFLO.The dynamic prediction shows that the results from TACITE are conservative than those from PIPEFLO.The simultaneous presence of gas and liquid flowing in pipeline with several uphill and downhill sections at Sulige 10 Block leads to the formation of terrain-induced slugging,which results in the transformation of flow characteristics(i.e.flow pattern);Liquid tends to build up at the lowest points of the pipeline,until it is forced onward through the rest of the pipeline by the pressure of the gas caught behind;Slugs from an upward inclined section can be carried over to downward inclined section after passing a top elbow,and the slug flow would exist or dissipate owing to change of flow characteristics.In pigging operation,pressures in the pipeline exceed normal value owing to the pig moving,that should be attached importance.2011,4(4): 1-5 收稿日期：2010-8-18分类号：TE86作者简介：王荧光(中油辽河工程有限公司,辽宁盘锦124010)参考文献：
