DOWNHOLE APPARATUS WITH PACKER CUP AND SLIP |
摘要 |
A downhole apparatus and assembly for use in a well bore and associated method are disclosed. The downhole apparatus includes a mandrel, a first slip, and a second slip, both slips being disposed on the mandrel. The slips are configured to grippingly engaging the well bore when in a set position. A packer cup is also disposed on the mandrel. The packer cup is provided for sealing an annulus between the mandrel and the well bore. The packer cup is slidable relative to the mandrel, and can be controlled to slide along the mandrel in order to move the slip to the set position. The downhole assembly includes a downhole tool and a setting apparatus. The setting apparatus can be used to lower the downhole apparatus to a desired setting depth and then to release the downhole apparatus.
