摘　　要：应用HYSYS和PIPESYS软件分析了凝析气集气管道的运行状态,结果表明,凝析气在较低的压力下为气-液两相流,在较高的压力下,为单相流(气相),压力继续增大时,则同时存在单相流和两相流,并有段塞流产生。借助HYSYS软件得到凝析气的相平衡图,并以此对上述现象进行了分析。指出在运行条件允许的情况下,可以提高起点温度来避免段塞流的形成,保证管道正常运行。The operation condition of condensate gas gathering line is analyzed with HYSYS and PIPESYS software. The results show that the condensate gas is respectively gas-liquid two phase flow and single phase flow (gas phase)at lower pressure and higher pressure. However, when pressure continuously increases,the single phase flow and two phase flow simultaneously exist in the condensate gas,and the slug flow,at this time,comes into being. By means of the phase equilibria relations,the authors analyze the above phenomena,and point out that the original temperature of pipeline can be increased to avoid the slug flow to protect pipeline under the permissible operation condition.
