摘　　要：为降低钻井成本 ,各油田采用尾管完井已很普遍。然而 ,生产应用中发现 ,这种完井工艺尚存在许多问题。突出问题是悬挂器坐挂失效 ,给现场施工人员带来许多麻烦。文中从悬挂器受力分析角度出发 ,借用数学工具 ,探讨了悬挂器自锁条件及与悬挂负荷有关的几个因素 。In order to reduce the drilling cost,liner completions is used widely in oilfield in recent years.However,there are many problems in the deployment for this completion technology.Among of them,the hanger set failure is the protruding problem,which leads to many troubles for the operators.On the basis of the analysis of the hanger force,this paper discusses the hanger selflocking condition and some factors about the hanging load.Finally,the causes of the hanger set failure are analysed.

关 键 词：悬挂器 自锁条件 悬挂负荷 失效形式 油井 完井
