Abstract

A tool includes a shaft having a front end and a distal end; a displacement mechanism for extending and retracting the shaft; and one or more pivoting tool elements coupled to the tool shaft proximate to the distal end of the shaft, wherein the one or more pivoting tool elements includes a body having an upper element and a lower element, wherein the one or more pivoting tool elements includes a pivot point about which the upper element and lower element pivot while coupled to the shaft. A method includes extending the tool shaft and the pivoting tool element into a bore of the flow control device; pivoting the pivoting tool element while extending the tool shaft through a removable component of the flow control device; and removing the removable component from the flow control device by retracting the tool shaft through the bore of the choke.

First claim

What is claimed is:

1. A tool configured for removal of a component from a flow control device, the tool comprising:
a shaft having a front end and a distal end;
a displacement mechanism for extending and retracting the shaft, wherein the displacement mechanism is coupled to the front end of the shaft; and
a pivoting tool element coupled to the shaft proximate to the distal end of the shaft,
wherein the pivoting tool element comprises a body having an upper element and a lower element,
wherein the pivoting tool element has a pivot point about which the upper element and lower element pivot while coupled to the shaft,
wherein the upper element is heavier than the lower element, and
wherein the lower element further comprises an opening.

2. The tool of claim 1 , wherein the upper element includes a protruding end that is in a direction opposite to a protruding end of a lower element.

3. The tool of claim 1 , wherein a top side or a bottom side of the pivoting tool element is tapered.

4. The tool of claim 1 , wherein the pivoting tool element is coupled a side of the shaft.

5. The tool of claim 1 , wherein the displacement mechanism further includes a threaded sleeve that encases a portion of the tool shaft.

6. The tool of claim 5 , wherein the threaded sleeve is coupled to a threaded nut.

7. A method comprising:
coupling the tool, according to claim 1 , to a flow control device;
extending the tool shaft and the pivoting tool element into a bore of the flow control device;
pivoting the pivoting tool element while extending the tool shaft through a removable component of the flow control device; and
removing the removable component from the flow control device by retracting the tool shaft through the bore of the flow control device.

8. The method of claim 7 , wherein the pivoting the pivoting tool element comprises contacting a front surface of the removable component with the pivoting tool element, wherein contacting the front surface of the removable component causes the pivoting tool element to pivot about the pivot point.

9. The method of claim 7 , wherein the removing the removable component further comprises contacting a back surface of the removable component with a front surface of the pivoting tool element as the tool shaft is retracted from the bore.

10. The method of claim 7 , further comprising actuating the displacement mechanism to extend the tool shaft through the bore of the flow control device.

11. The method of claim 7 , further comprising attaching the tool shaft to a front side of the flow control device.

12. The method of claim 7 , further comprising, replacing the one or more pivoting tool elements with an installation tool element for installing the component in the bore of the flow control device.

13. A system comprising:
a flow control device having a bore and a removable component disposed in the bore, wherein the removable component comprises a bore in fluid communication with the bore of the flow control device; and
the tool according to claim 1 .

14. The system of claim 13 , wherein a height of the one or more pivoting tool elements is greater than a smallest inner diameter of the component.

15. The system of claim 13 , wherein the displacement mechanism is comprised of a threaded sleeve coupled to a front end of the tool shaft and a threaded nut coupled to the threaded sleeve.

16. The system of claim 13 , further comprising an attachment mechanism for attaching the component removable tool to a front face of the flow control device.

17. The system of claim 16 , wherein the component removal tool is coupled to the attachment mechanism.

18. The system of claim 16 , wherein the attachment mechanism includes a ring that is threadably engaged with threads located on a front face of the flow control device.
