Tubular handling methods
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.
1. A method of handling a tubular in a casing or drilling operation, comprising:
operating a running tool to interact with and grip a tubular section comprising at least one tubular;
applying a rotational force to the tubular section, at least one surface of which is engaged with and gripped by a portion of the running tool, to at least partially disconnect the tubular section from a tubular string;
operating a tubular member elevator to interact with and grip the tubular section or a portion thereof; and
raising the tubular section relative to the running tool to separate the tubular section from the tubular string and to disengage the engaged and gripped at least one surface of the tubular section from the portion of the running tool.
2. The method of claim 1 , the operating the tubular member elevator further comprising:
confirming that the tubular section or the portion thereof is gripped by the tubular member elevator using a control device; and
automatically beginning raising the tubular section relative to the running tool as a result of confirming that the tubular section or the portion thereof is gripped.
3. The method of claim 1 , the operating the running tool further comprising:
lowering the running tool over a stump comprising the at least one tubular until at least a portion of the tubular is inserted into the running tool; and
extending a running tool actuator coupled to the running tool and the tubular member elevator relative to the running tool in a direction parallel to a length of the tubular.
4. The method of claim 3 , further comprising:
reversibly exerting force on an axial end of the tubular with the at least portion of the tubular inserted into the running tool so as to set the grip on the tubular section; and
raising the running tool, relative to a floor slip, while the grip is set on the tubular section.
5. The method of claim 1 , further comprising:
retracting, after the disconnection, a running tool actuator coupled to the running tool and the tubular member elevator relative to the running tool to disengage the engaged and gripped at least one surface of the tubular section from the portion of the running tool; and
extending, after the retracting, the running tool actuator relative to the running tool until the at least one surface of the tubular section is extracted from the running tool.
6. The method of claim 1 , further comprising:
tilting the separated tubular section away from a coaxial position to the tubular string to an orientation relative to a pipe storage structure; and
releasing the grip on the tubular section or a portion thereof by the tubular member elevator.
7. The method of claim 1 , the raising the tubular section further comprising:
lowering the running tool onto an axial end of a stump of the tubular string to fully disengage the engaged and gripped at least one surface of the tubular section from the portion of the running tool.
8. A method of handling a tubular in a casing or drilling operation, comprising:
operating a running tool to interact with a tubular section comprising a tubular;
applying a rotational force to the tubular section, at least one surface of which is engaged with and gripped by a radially-shaped segment of the running tool, to at least partially disconnect the tubular section from a tubular string;
operating a tubular member elevator to interact with and grip the tubular section or a portion thereof; and
moving the radially-shaped segment of the running tool in a direction having at least an axial component along the gripped tubular section, in response to the tubular section moving in the direction having the at least axial component, to disengage the radially-shaped segment of the running tool from the at least one surface of the tubular section.
9. The method of claim 8 , further comprising:
removing the tubular section entirely from a tubular handling apparatus.
10. The method of claim 8 , further comprising:
confirming that the tubular section or the portion thereof is gripped by the tubular member elevator using a control device; and
automatically moving the radially-shaped segment of the running tool as a result of confirming that the tubular section or the portion thereof is gripped.
11. The method of claim 8 , further comprising:
retracting an extended running tool actuator relative to the running tool in the direction having the at least axial component, the running tool actuator being coupled to the running tool and the tubular member elevator as the tubular member elevator is gripping the tubular section or the portion thereof.
12. The method of claim 11 , further comprising:
extending, after the retracting, the running tool actuator relative to the running tool until the tubular section is extracted from the running tool.
13. The method of claim 8 , further comprising:
lowering the running tool onto an axial end of a stump of the tubular string to fully disengage the radially-shaped segment of the running tool from the at least one surface of the tubular section.
14. A method of handling a tubular in a casing or drilling operation, comprising:
grasping a tubular section of the tubular with a tubular member elevator, the tubular having an axial end;
orienting the tubular section relative to a running tool;
operating the running tool to frictionally engage and grip the tubular section;
actuating a pre-load mechanism that is adapted to exert an axial force on the tubular in an axial direction when the tubular is engaged in the running tool, the axial force increasing a gripping strength on the tubular; and
applying a rotational force to the tubular section while it is engaged and gripped by the running tool to connect the tubular section to a tubular string.
15. The method of claim 14 , wherein applying a rotational force to the tubular section comprises:
applying a rotational force to the running tool to rotate the running tool and the tubular section gripped by the running tool.
16. The method of claim 14 , further comprising:
disengaging the tubular member elevator from the tubular section prior to applying the rotational force to the tubular section.
17. The method of claim 14 , wherein actuating the pre-load mechanism comprises:
disengaging the tubular member elevator after gripping the tubular with the running tool.
18. The method of claim 14 , further comprising:
lowering the tubular gripped by the running tool onto a load-bearing surface to further urge an end of the tubular into a recess in the running tool.
19. The method of claim 14 , wherein orienting the tubular section comprises:
lowering the running tool while concurrently raising the tubular section with the tubular member elevator.
