摘　　要：为保证深水气田高效开发和安全运行,使各井区产能充分释放,建立“井筒-井口-管汇-平台”一体化稳态模型。基于配产方案,从产量验证、水合物防治、段塞分析、携液分析等方面开展研究。结果表明:全生命周期内东西区生产路由均有水合物生产风险,通过优化各井嘴后MEG(乙二醇)贫液注入量,生产路由最大水合物过冷度均小于-5℃。东西区物流登平台温度为-2.4~9℃,登平台压力为1.3~11 MPa。研究成果可为后续类似深水气田的高效开发提供技术指导。In order to ensure the efficient development and safe operation of deep water gas field and fully release the production capacity of each well area,the integrated steady-state model of“wellbore-wellhead-manifold-platform”was established.Based on the production plan,the research was carried out from the aspects of production verification,hydrate prevention and control,slug analysis and liquid carrying analysis.The results show that there are hydrate production risks in the whole life cycle in the east and west production routes.The maximum hydrate sub-cooling degree in the production route is less than-5℃by optimizing the MEG injection amount in each well.The platform temperature of eastern and western logistics is-2.4~9℃,and the platform pressure is 1.3~11 MPa.The research results can provide technical guidance for the effective development of similar deep water gas fields in the future.
