摘要： An expandable downhole tool such as an under-reamer or a stabiliser includes a mandrel mounted for linear slidable movement relative to a main body. The mandrel, together with one or more travel blocks, cause movement of a working component in an axial direction. One or more outwardly extending guide paths slidably interact with the working component to cause the working component to move between a withdrawn inoperative position and an outwardly deployed operative position. Upon increase of hydraulic pressure from below the tool, the mandrel is urged against a spring biasing the deactivated position to move axially and cause the working component to take its operative position. Upon decrease of hydraulic pressure, the spring moves the mandrel axially to cause the working component to take its withdrawn inoperative position.

摘要： An activating device is mounted in a drill string to control the activation and deactivation of an enlargement tool used for enlarging a bore hole. In order to assemble the activating device, pistons are mounted in passages and spline bars, in which plates are screwed, are then slid along T-slots of the body, through apertures of the pistons. In order to deploy the pistons and cutters, pressurized drilling fluid is applied to the inner faces of the pistons. When a pre-determined pressure level is reached, screws break and the pistons move from the inward position to the outwardly deployed position.

摘要： A packer apparatus is disclosed. Packer apparatus comprises a body configured to be disposed in a wellbore and a deformable packer element disposed on the body. The deformable packer element comprises a deformable metallic outer cover. An actuation apparatus is configured to move relative to the body to deform said deformable packer element outwardly from the body to cause the deformable metallic outer cover to contact the surface of the wellbore or casing in which the apparatus is located. Deactivation of the actuation apparatus causes the deformable packer element and deformable metallic outer cover to return to a retracted condition.
