    • A method and assembly for completing a well is disclosed. Generally, the method comprises the steps of positioning a stationary string in the well at a first position. The stationary string will have connected thereto a completion device for completing the well to a reservoir and a detachment apparatus for detaching the completion device from the stationary string. The method further comprises the steps of positioning a secondary string in the well, with the secondary string having a cooperating detachment apparatus for detaching the completion member from the stationary string. Next, the completion member is detached from the stationary string and attached to the secondary string, and the completion member is positioned at a second position which corresponds to a hydrocarbon zone. In one embodiment, the stationary string is a production tubing string, and the production tubing is attached to an isolation safety valve member for isolating the well from pressure.
    • 公开了一种用于完井的方法和组件。 通常,该方法包括以下步骤:在第一位置将定位柱定位在井中。 固定的绳子将连接到一个完井装置,用于将油井完成到储存器中,以及用于将完井装置从静止柱上分离的拆卸装置。 该方法还包括以下步骤:将次级串定位在井中,其中次级串具有用于将完成构件与固定绳分离的配合拆卸装置。 接下来,将完成部件从静止的线分离并安装在次级线上,完成部件位于对应于烃区的第二位置。 在一个实施例中,固定管是生产油管柱,并且生产管连接到隔离安全阀构件,用于隔离井与压力。
