摘要： A ferromagnetic fluid can be used to provide a temporary barrier in a wellbore. A magnetic sub can generate an electromagnetic field within the wellbore. The ferromagnetic fluid is retained at a desired location within the wellbore by the electromagnetic field. Ferromagnetic particles in the fluid can clump together or settle to form the temporary barrier. A zonal isolation fluid such as a metallic fluid, a cement composition, or a curable resin composition can be introduced on top of the temporary barrier. The zonal isolation fluid can solidify to form a permanent or semi-permanent barrier to provide zonal isolation of different zones of the subterranean formation.

摘要： A packer assembly is located in a compacted wellbore and a method of relieving compression on the packer assembly are disclosed. An initial load path that exists when the packer assembly is in a set position is altered. The alteration of the load path relieves substantially all of the compression on the packer assembly. This causes a lower packer mandrel to move towards an upper packer mandrel. This upward movement shortens the distance between the upper packer mandrel and the lower packer mandrel, which removes the compressive forces on the packer assembly.
摘要翻译：封隔器组件位于压实的井眼中，并且公开了一种对封隔器组件进行压缩的方法。当封隔器组件处于设定位置时存在的初始加载路径被改变。负载路径的改变基本上减轻了封隔器组件上的所有压缩。这导致较低的封隔器心轴向上封隔器心轴移动。这种向上运动缩短了上封隔器心轴和下封隔器心轴之间的距离，从而消除了封隔器组件上的压缩力。
