Abstract

Claims (49)

1 . A setting tool for setting a downhole component of a downhole tool, comprising:

a setting housing connectable to the downhole tool, the setting housing having a passage therethrough;

a setting assembly positioned in the passage, the setting assembly comprising a drive portion and a deployment portion, the drive portion having an elongate body with a propellant chamber therein, the deployment portion having an elongate body with an opening at a driver end thereof defining a drive cavity shaped to slidingly receive an end of the drive portion therein, the deployment portion comprising a deployment end, the deployment end connectable to the downhole component for movement therewith; and

an integrated igniter positioned in the propellant chamber, the integrated igniter comprising an igniter housing, a switch assembly, and an internal propellant, the switch assembly operatively connected to the internal propellant whereby, upon triggering the switch assembly, the internal propellant is ignited to release an ignition fluid under ignition pressure to move the deployment portion and the downhole component connected thereto to an activated position;

wherein the integrated igniter has an external propellant and wherein the external propellant is one of:

supported by the igniter housing and extending a distance therefrom; and

positioned outside the integrated igniter and within the propellant chamber.

2 . The setting tool of claim 1 , wherein the setting housing comprises an integrated thread adapter and an outer chamber connected together.

3 . The setting tool of claim 2 , wherein the integrated thread adapter is connected to another downhole component of the downhole tool and the outer chamber is connected to the downhole component.

4 . The setting tool of claim 1 , wherein the drive portion comprises a propellant chamber rod, a drive piston, and a drive end, the propellant chamber rod having the propellant chamber therein shaped to receive the integrated igniter, the drive end positioned at an end of the propellant chamber rod, the drive piston slidingly movable along an outer surface of the propellant chamber rod.

5 . The setting tool of claim 4 , wherein the deployment portion further comprises a deployment rod and a deployment end, the deployment end connected to the deployment rod and slidably positioned within the setting housing.

6 . The setting tool of claim 5 , wherein the deployment rod is connected to the drive piston and is movable therewith.

7 . The setting tool of claim 6 , wherein the deployment rod comprises a deployment chamber and a fluid chamber connected together, the driver end of the deployment chamber connected to the drive piston, the fluid chamber connected between the deployment chamber and the deployment end.

8 . The setting tool of claim 7 , wherein the fluid chamber has a cushion fluid therein, the ignition pressure applied to the cushion fluid whereby the ignition pressure is reduced.

9 . The setting tool of claim 7 , wherein the propellant chamber rod has a vented end with perforations to allow fluid pressure in the propellant chamber rod to pass from the propellant chamber, through the drive end, and to the drive piston.

10 . The setting tool of claim 1 , wherein the internal propellant is positioned within the igniter housing.

11 . The setting tool of claim 1 , wherein:

the igniter housing comprises an igniter portion and a nose portion, the igniter portion having a switch chamber therein, the nose portion having a propellant opening therethrough;

the switch assembly is positioned in the switch chamber, the switch assembly comprising a switch movable between an untriggered and a triggered position; and

the propellant is supported by the nose portion, the propellant connected to the switch and the integrated igniter thereby when the switch is moved to the triggered position whereby the propellant releases a gas through the propellant opening to activate the downhole component.

12 . A downhole tool, comprising:

a downhole component; and

a setting tool for setting the downhole component, the setting tool, comprising:

a setting housing connectable to the downhole tool, the setting housing having a passage therethrough;

a setting assembly positioned in the passage, the setting assembly comprising a drive portion and a deployment portion, the drive portion having an elongate body with a propellant chamber therein, the deployment portion having an elongate body with an opening at a driver end thereof defining a drive cavity shaped to slidingly receive an end of the drive portion therein, the deployment portion comprising a deployment end, the deployment end connectable to the downhole component for movement therewith; and

an integrated igniter positioned in the propellant chamber, the integrated igniter comprising an igniter housing, a switch assembly, and an internal propellant, the switch assembly operatively connected to the internal propellant whereby, upon triggering the switch assembly, the internal propellant is ignited to release an ignition fluid under ignition pressure to move the deployment portion and the downhole component connected thereto to an activated position;

wherein the integrated igniter has an external propellant and wherein the external propellant is one of:

supported by the igniter housing and extending a distance therefrom; and

positioned outside the integrated igniter and within the propellant chamber.

13 . The downhole tool of claim 12 , wherein the downhole component comprises a plugging tool.

14 . The setting tool of claim 13 , wherein the plugging tool comprises a plug tube and a plug, the plug tube connected to the driver end, the plug radially expandable from the plug tube and against a wall of a wellbore whereby a portion of the wellbore is sealed.

15 . The downhole tool of claim 12 , wherein the external propellant is positioned in the propellant chamber about a nose portion of the integrated igniter.

16 . The downhole tool of claim 15 , wherein the external propellant comprises one of stacked discs and a solid member.

17 . A method of setting a downhole component of a downhole tool, comprising:

positioning an integrated igniter into a setting tool, the integrated igniter comprising an igniter housing, a switch assembly, and a propellant;

positioning the setting tool about a plugging tool of the downhole tool;

positioning the downhole tool in a wellbore; and

deploying a plug against a wall of a wellbore by activating the setting tool with the integrated igniter by:

sending a trigger signal from the surface to the switch assembly such that the propellant is ignited and releases pressurized fluid into the setting tool thereby shifting the setting tool and the plugging tool connected thereto to an activated position;

wherein the integrated igniter has an external propellant and wherein the external propellant is one of:

supported by the igniter housing and extending a distance therefrom; and

positioned outside the integrated igniter and within a propellant chamber of the setting tool.

18 . The method of claim 17 , further comprising:

driving a drive piston with the pressurized fluid, and

driving a plug piston by transferring movement of the drive piston to the plug piston.

19 . The method of claim 17 , further comprising retracting the downhole tool with the integrated igniter from the wellbore.

20 . The method of claim 17 , further comprising replacing the propellant and portions of the integrated igniter.

21 . The method of claim 17 , further comprising releasing a pressurized gas by exploding the propellant within the setting tool.

22 . The method of claim 21 , further comprising: upon igniting the propellant, driving a drive piston with the pressurized gas, and driving a plug rod connected to the setting tool by transferring movement of the drive piston to a plug piston of the plug.
