摘　　要：近年来,水平井技术逐步大量应用,但水平井产量递减快,底水上升快,找水、堵水困难等问题也成为影响水平井长期稳产的关键问题。如何最大程度地保证水平段的各个部分能够均衡生产,实现控水已成为水平井开发中极其重要的课题之一。针对该问题,介绍了当前国内外现有的多种水平井控水完井技术,如分段变密度筛管控水完井、中心管控水完井、ICD控水完井、DWS控水完井、倾斜井筒控水完井等。智能化控水完井将成为水平井控水完井技术的发展趋势。In recent years,the horizontal well technologies are used widely.But the production rate of horizontal well de-creases quickly and the basal water rise rapidly,it is very difficult to plug water.These questions have become the key problems which influence the stable production of horizontal well.How to ensure balance production at every horizontal section,and realize water-controlling completion has become a vital subject in horizontal well development.Aiming at the question,the existing water-controlling completion technologies at home and abroad were introduced,such as completing with variable density liner,central tube,DWS or ICD,and so on.The intelligentize water-controlling completion will be the development trend of this technology.
