摘　　要：为了提高乙二醇管理水平和确保管道运行的安全,以目前具有代表性的荔湾3-1气田为例,利用成熟的OLGA商用软件,模拟研究分析了管输量改变对乙二醇贫液加注及富液再生的影响,分析获得了以下结论:(1)在减输过程中,管道积液量增大,为达到新的平衡需增加乙二醇贫液的储存量;(2)在增输过程中,大量积液被顶出管道,对平台液相分离能力提出了更高的要求,应增强乙二醇富液的储存和处理能力。并建议随着输量调整幅度增大,宜采取多阶段递阶式缓解液涌的调整策略,达到新平衡态所需时间延长。For the sake of increasing ethylene-glycol management level and ensuring pipeline safe operation, taking Liwan 3-1 gasfield as an example, this study analyzed the effect of transportationvolume variation on both lean-solution injection and rich-solution regeneration by means of a mature OLGA software. Results show that(1) because liquid volume may increase in the process of lowering transportation, it's necessary to raise storage volume of ethylene glycol lean solution in order to maintain a new balance; and(2)since large amount of liquid volume is knocked out during increasing transportation, the storage and processing capability of ethylene glycol rich solution should be enhanced to implement a liquidphase separation. In addition, it is suggested that, with an increase of transportation-volume adjustment, a strategy to relieve liquid flood in a multi-stage and hierarchical way ought to be adopted in order to prolong the time for achieving the balance.
