ZERO-RELAXATION PACKER SETTING LOCK SYSTEM |
摘要 |
A packer mandrel is radially surrounded by an axially compressible packer element and a backing ring. A setting sleeve arrangement also surrounds the packer mandrel adjacent the packer element. A hydraulic locking mechanism is used to secure the setting sleeve arrangement against the packer element. The hydraulic locking mechanism includes an expansible fluid-sealed chamber that is defined between the setting sleeve and the central packer mandrel.
