摘要： The present invention relates to packers adapted to seal an annular space within a wellbore. The packers, for example, may be utilised to circulate or reverse circulate a fluid. In one embodiment, the present apparatus (100) comprises a first tubular subunit (102) and a second tubular subunit (103) moveably coupled together, a flexible packing element (106) disposed between the first tubular subunit and the second tubular subunit, and a temporary mechanical connection adapted to restrain the first tubular subunit and the second tubular subunit from compressing the flexible packing element, in which the temporary mechanical connection is adapted to be hydraulically disengaged. In another embodiment, the present apparatus further comprises a valve (150). In one aspect, the present apparatus further comprises a cement inflation tool.

摘要： A method for reclaiming a borehole extending from an earth surface into the earth, part of which borehole is in a lost circulation zone, includes closing off the borehole to fluid flow above the lost circulation zone by installing a packer system with an inflatable packer element, a plurality of ribs (304) mounted around the inflatable packer element, and a valve apparatus (120) in the borehole above the lost circulation zone, the packer system being made of drillable material, inflating the inflatable packer element with cement, and allowing the cement to set so that the inflatable packer and the valve apparatus effectively seal off the borehole to fluid flow.

In another embodiment, the present apparatus further comprises a valve (150). In one aspect, the present apparatus further comprises a cement inflation tool. In still another embodiment, the present method comprises locating an apparatus, comprising a packer and a valve positioned above the packer, at a predetermined location within the wellbore; setting the packer, the method of setting the packer comprising, applying a first hydraulic pressure within a central bore of the apparatus and applying down weight on the apparatus; and opening the valve. In one embodiment, the present method comprises actuating a displacement device to displace a fluid below a packer; setting the packer by utilising a predetermined fluid pressure to disengage a temporary mechanical connection between a first surface and a second surface of the packer and by compressing a packing element between the first surface and second surface; and opening a valve above the packer.

摘要： Apparatus for attaching a downhole isolation, production, or testing tool is disclosed such that the tool is mechanically attached to a mandrel in a manner that is highly resistant to axial movement. The mechanical connection resists high temperatures, high pressures, and corrosive fluids and gases that may be encountered in the well without the use of welding to a casing mandrel. In general, the connection includes at least one groove or channel (48) cut in an outer wall of the casing mandrel, and at least one partially or fully annular slot (62) on the inside surface of the tool oriented to correspond with the groove(s) in the outer wall of the casing mandrel. At least one lock (64) is situated in the corresponding slot (62) and the groove (48). The lock (64) engages the flanks of the slot (62) and groove (48) sufficiently to resist shears loads applied by compression or tension in the string, and thereby restrains axial movement of the valve assembly relative to the casing mandrel. In one embodiment, the lock is one or more wires (64), although other mechanical locking devices may be installed to provide the same function.
