Vibrating downhole tool
A vibrating downhole tool comprising a housing, an inner mandrel disposed within the housing and configured to receive a drilling fluid, a mass coupled to the inner mandrel, and a plurality of turbine blades configured to receive the drilling fluid and to rotate the inner mandrel and the mass, thereby causing the vibrating downhole tool to vibrate.
1. A vibrating downhole tool comprising:
a housing;
an inner mandrel disposed within the housing and configured to receive a drilling fluid;
a mass coupled to the inner mandrel; and
a plurality of turbine blades configured to receive the drilling fluid and to rotate the inner mandrel and the mass, thereby causing the vibrating downhole tool to vibrate;
a sliding sleeve coupled to the mass and configured to axially reciprocate to provide axial displacement of the downhole tool.
2. The vibrating downhole tool of claim 1 , comprising a flow control device configured to control the flow of the drilling fluid through the plurality of turbine blades and the inner mandrel.
3. The vibrating downhole tool of claim 2 , wherein the flow control device includes one of the group consisting of a valve and a drop ball nozzle.
4. The vibrating downhole tool of claim 1 , comprising at least one bearing disposed between the inner mandrel and housing.
5. The vibrating downhole tool of claim 1 , wherein the housing includes an annular port configured to allow the drilling fluid to be released from the vibrating downhole tool.
6. The vibrating downhole tool of claim 1 , wherein the sliding sleeve is configured to translate along an axis of the inner mandrel as the mass is rotated.
7. The vibrating downhole tool of claim 1 , wherein a rotation of the mass is configured to vibrate the downhole tool.
8. A drilling tool assembly comprising:
a drill string;
a drill bit coupled to the drillstring; and
at least one vibrating downhole tool coupled to the drill string, the vibrating downhole tool comprising:
a housing;
an inner mandrel configured to receive a drilling fluid;
a mass coupled to the inner mandrel;
a plurality of turbine blades configured to receive the drilling fluid and to rotate the inner mandrel and the mass, thereby causing the vibrating downhole tool to vibrate; and
a sliding sleeve coupled to the mass and configured to axially reciprocate to provide axial displacement of the downhole tool.
9. The drilling assembly of claim 8 , further comprising a jar coupled to the drill string.
10. The drilling assembly of claim 8 , further comprising a flow control device configured to control the flow of the drilling fluid through the turbine of the vibrating downhole tool.
11. The drilling assembly of claim 8 , wherein the flow control device includes one of a group consisting of a valve and a drop ball nozzle.
12. A method of activating a vibrating downhole tool, the method comprising;
pumping a fluid downhole through a drill string to the vibrating downhole tool; and
selectively activating the vibrating downhole tool by actuating a flow control device proximate the vibrating downhole tool, thereby allowing the fluid to flow through the vibrating downhole tool;
axially reciprocating a sliding sleeve along an axis of an inner mandrel of the vibrating downhole tool.
13. The method of claim 12 , wherein the flow control device comprises one of the group consisting of a valve and a drop ball nozzle.
14. The method of claim 12 , further comprising rotating a mass by allowing the fluid to pass through a plurality of turbine blades, thereby causing the vibrating downhole tool to vibrate.
15. A method of freeing drilling equipment stuck within a wellbore, the method comprising:
pumping a fluid downhole through a drill string;
diverting the fluid to flow through a plurality of turbine blades of the vibrating downhole tool;
rotating an inner mandrel and a mass through the use of the plurality of turbine blades;
axially reciprocating a sliding sleeve coupled to the mass; and
vibrating at least one component of the drill string.
16. The method of claim 15 , further comprising actuating a flow control device configured to selectively divert the fluid to flow through the plurality of turbine blades.
17. The method of claim 15 , further comprising increasing a flow rate of the fluid through the plurality of turbine blades, thereby increasing a frequency of vibration of the at least one drill pipe.
18. The method of claim 15 , further comprising reducing a flow rate of the fluid through the plurality of turbine blades, thereby decreasing a frequency of vibration of the at least one drill pipe.
19. The method of claim 15 , further comprising providing the at least one component of the drill string with a radial vibration.
