摘　　要：海上油田主要以水平井开发为主,如何有效控制含水上升速度是各油田面临的主要问题之一。海上油田应用的机械控水完井技术包括中心管控水、变密度筛管控水、ICD/AICD分段控水、充填调流控水、C-AICD控水、找控水一体化等。总结了各方法的技术原理、优缺点和适用范围,其中充填调流控水和ICD分段控水是海上油田主要应用的两种机械控技术,前者利用轻质覆膜颗粒作为轴向封隔材料,适用于地层非均质性强、水平段长的油井控水,广泛应用于渤海和南海东部油田;而ICD分段控水技术需要准确设计封隔器坐封位置,因此适用于地层情况认识清楚、非均质性不强的油井控水,主要应用于南海东部油田。基于技术现状,展望了机械控水完井技术的发展趋势,分析结果可为海上油田控水完井方式的选择和后续技术的发展提供借鉴。Offshore oilfields are typically developed using horizontal wells.One of the main challenges faced by each oil field is effectively controlling the rate of water content rise.Mechanical water control completion technologies used in offshore oilfields include central water contro,variable density screen water control,ICD/AICD stage water control,filling flow control water control,C-AICD water control,and water search and control integration.The text describes the technical principles,advantages,and disadvantages,as well as the application scope of each method.Two main mechanical control technologies used in offshore oil fields are filling flow control and ICD subsection water control.The first method utilizes light film-coated particles as axial sealing materials and is appropriate for water control in oil wells with strong formation heterogeneity and long horizontal sections.This method is widely used in oil fields located in the Bohai Sea and eastern South China Sea.On the other hand,ICD subsection water control technology necessitates precise design of packer setting position,making it suitable for oil well water control with clear formation conditions and low heterogeneity.The mechanical water-controlled completion technology is primarily utilized in the eastern oilfield of the South China Sea.The current technical situation and development trends of this technology are highlighted in this article.The results can be a reference for the selection of water control completion methods and the development of subsequent technologies in offshore oil fields.
