  • Liner hanger top packer
    Patent number: 9745809
    Abstract: A liner hanger top packer comprising a body and, an adjusting sleeve, a retaining apparatus, a base-sealing apparatus, a base-hanging apparatus and a locking mechanism sleeved sequentially from top to bottom on the body. The locking mechanism is arranged between the base-sealing apparatus and the base-hanging apparatus. The locking mechanism comprises a locking ball sleeve, a ball socket, and a steel ball. As the lower part of the liner hanger top packer is met with friction, the arrangement of the steel ball restricts relative axial movements between an upper gauge ring of the base-sealing apparatus, the locking ball sleeve, and an upper conical body of the base-hanging apparatus, the friction transmitted to the upper conical body is not transmitted to a lower gauge ring of the base-sealing apparatus, is transmitted to the upper gauge ring via the steel ball, and is transmitted to the adjusting ring via the retaining apparatus.
