摘　　要：尾管悬挂器是用来悬挂尾管并将尾管与上层套管相连接的装置,在尾管固井中具有重要作用。目前尾管固井日益增多,所使用的尾管悬挂器结构多种多样。在现场尾管固井实施过程中出现了环空不畅、替压过高和提前坐挂等井下复杂情况。介绍和分析了尾管悬挂器的结构、性能特点及优缺点,总结了在现场应用中易出现的事故预防及处理措施。Liner hanger is a device for liner hanging and connecting with upper casing,which is important in liner cementing. Along with increasing liner cementing operation,various structures of liner hanger are used. Annular plug,too high displacement pressure and advanced setting often occur in field liner hanger operation. The paper introduces and analyzes liner hanger about its structure,performance characteristics,advantages and disadvantages,summarizes the prevention and treatment measures for the accidents easily occurred in the field application.
