Abstract

A tubular handling apparatus including a tubular member running tool adapted to provide load-bearing, and preferably torquing, capacity upon the gripping of a tubular is provided. The running tool includes a slotted member having a plurality of elongated slots, a recessed member associated with the slotted member and having a plurality of recesses, and a plurality of gripping elements disposed between the slotted member and recessed member. Each such gripping element is adapted to move with an engaged tubular so as to grip the tubular. A tubular member elevator associated to the running tool, as well as related floor slips, are also encompassed. Methods of casing running are also included.

Claims (23)

1. A tubular handling apparatus, comprising:

a tubular running tool comprising:

a slotted member having a plurality of elongated slots each extending at least partially in a direction substantially parallel to a longitudinal axis of a tubular to be handled;

recessed member operably associated with the slotted member and having a plurality of recesses in a surface thereof that each extend between a deep end and a shallow end; and

a plurality of sliding members operatively associated with the plurality of elongated slots and the plurality of recesses, and adapted to move in the same direction as a tubular in contact therewith so that the tool grips the tubular;

a tubular member elevator adapted to operatively associate a tubular with the tubular running tool;

a pre-load mechanism that is adapted to reversibly exert force on the axial end of the tubular when engaged in the tubular running tool so as to grip the tubular; and

wherein the tubular running tool is adapted to grip each tubular to provide load-bearing capacity to inhibit or prevent the tubular or a tubular string attached thereto from dropping independently of the operation of the tubular member elevator.

2. The tubular handling apparatus of claim 1 , wherein the tubular member elevator is coupled to the tubular running tool and is adapted to transfer tubulars between a tubular supply and the tubular running tool.

3. The tubular handling apparatus of claim 2 , wherein the tubular running tool and tubular member elevator are coupled through no more than a pair of actuators.

4. The tubular handling apparatus of claim 3 , wherein the no more than a pair of actuators is operably associated with linking elements that facilitate positioning of a portion of the tubular within the tubular running tool.

5. The tubular handling apparatus of claim 1 , wherein the plurality of sliding members each retracts at least partially into a corresponding recess when the tubular handling apparatus is in a gripping position to grip a tubular.

6. A tubular running tool comprising:

a slotted member having a plurality of elongated slots each extending at least partially in a direction substantially parallel to a longitudinal axis of a tubular to be handled;

a recessed member operably associated with the slotted member having a plurality of recesses wherein the recesses extend from a deep end to a shallow end; and

a plurality of sliding members operatively associated with the plurality of elongated slots and the plurality of recesses;

a pre-load mechanism that is adapted to reversibly exert force on the axial end of the tubular when engaged in the tubular running tool so as to grip the tubular; and

wherein a gripping portion of the running tool is configured to frictionally engage at least one surface of a tubular sufficient to apply a torque to the tubular solely through the gripping portion.

7. The tubular running tool of claim 6 , wherein the plurality of elongated slots are fixed relative to the plurality of recesses.

8. The tubular running tool of claim 6 , wherein the running tool is configured to frictionally engage an inner surface of a tubular.

9. The tubular running tool of claim 6 , wherein the plurality of sliding members each retract partially into a corresponding slot and recess when the tubular handling apparatus is in a release position so as not to grip a tubular.

10. The tubular running tool of claim 6 , wherein the plurality of sliding members are adapted to grip a tubular upon the motion of the tubular away from the running tool.

11. The tubular running tool of claim 6 , wherein the tubular running tool is operatively associated with a handling mechanism that is adapted to feed a tubular into, or remove a tubular from, the running tool so as to facilitate iterative loading of the running tool with a further tubular.
