摘　　要：稠油热采注汽锅炉水质要求高,常规锅炉供给水处理系统流程长、占地大、操作维护复杂,难以应用于海上平台热采生产。调研海水淡化流程,基于海上油田生产和环境特点研究适用于海上平台稠油热采的海水淡化方案,通过对比海水预处理方案、脱氧方案并分析不同干度的脱盐方案,提出不同蒸汽干度指标的锅炉给水处理系统流程。研究成果已应用于渤海某油田稠油热采开发的设计和工程实施中,为稠油规模化热采锅炉给水处理系统的设计提供参考和建议。Regular boiler feed water treatment system is not suitable for offshore thermal recovery platform because of its characters of long procedure of process,large area occupation and complicated maintenance.Seawater desalination plan fit for offshore platform is studied based on offshore production and environmental features.Boiler feed water treatment systems that can produce steam of different dryness are proposed by comparing the seawater pretreatment schemes,deoxidation schemes and desalination schemes.The schemes proposed in this study has been applied in the design and construction of Bohai Oil Field thermal recovery and offer practical references of boiler feed water treatment system design.
