摘　　要：海上气田在正常生产中由于受温度、压力、流动条件突变等因素影响,可能会形成天然气水合物,从而引发管道堵塞、设备超压等生产事故,为了防止水合物的生成,通常采取注入乙二醇进行水合物抑制。本文结合实际的高压天然气田开采工程经验,得出水合物形成的三个主要工况—正常生产工况、长时间关井工况、关井再启动工况,运用ASPEN HYSYS模拟与Hammerschmidt公式计算相结合的方法分析水合物的形成和乙二醇的注入,解决了工程实际问题,对类似高压气田的开发有重要的借鉴意义。Due to influence of temperature, pressure, flow condition change, the natural gas hydrate may form during normal natural gas production, which will cause pipe blockage, overpressure of equipment and other production accidents. In order to prevent hydrate formation, ethylene glycol is usually injected into the natural gas field. In this paper, according to actual engineering experience of high pressure gas field production, three major conditions of hydrate formation were got, including normal production condition, shut-in condition, and restart up condition. Then ASPEN HYSYS model and Hammerschmidt formula were creatively used to analyze the hydrate formation and ethylene glycol injection, the practical engineering problems were solved, which can provide successful experiences for development of other high pressure gas fields.
