摘要: 与常规尾管悬挂器相比,可膨胀尾管悬挂器具有诸多优势。可膨胀尾管悬挂器是一种连接在尾管上,通过地面操作进行液压或机械作用,使得膨胀管沿径向膨胀的一种尾管悬挂器。通过膨胀管本体的膨胀,膨胀管本体与外层套管进行贴合,在摩擦力的作用下,进行尾管的悬挂,并进行有效密封;同时,保证了良好的井眼尺寸,为后续井下操作提供技术保证。由于其具密封能力强、悬挂能力优、可旋转固井、尾管入井过程中可开泵循环等优点,能解决超深井、大位移井以及水平井的尾管下入和水泥顶替效率低等技术难题,因而具有广阔的应用前景。本文将对国内外膨胀尾管悬挂器技术现状进行简述,并对西部钻探钻井工程技术研究院进行自行研制的膨胀尾管悬挂器的结构及工作原理及相关配套技术进行论述。

Abstract: Expandable liner hangers (ELH) have been shown to provide multiple advantages over conventional liner hangers. The expandable liner hanger (ELH) will be expanded by the hydraulic action or mechanical action. The ex-panded body of the ELH can hang the liner reliably. At the same time, the ELH can provide some advantages, such as good seal and hang liner abilities, rotating cementing, etc. The ELH can also resolve some technical difficulties which occur when tripping in liners and cement displacements in ultra-deep wells, extended reach wells and horizontal wells. So, the expandable liner hanger has a broad prospect in applications. The paper aims to introduce the characteristics, operating principles and matching technologies of the Expandable Liner Hanger which is developed by Drilling Tech-nology Research Institute of Xibu Drilling Engineering Company, CNPC.
