Abstract

A axial retention connection for a downhole tool is disclosed. The connection includes a drill string component including a socket having a plurality of walls and a top surface. The connection additionally includes a downhole tool coupled to the socket, the downhole tool including a male-type connector having an outer perimeter and a top surface. The connection further includes a seal between the drill string component and the downhole tool. The connection further includes a chamber formed by the plurality of walls and the top surface of the socket and the top surface of the male-type connector; and a fluid filling the chamber.

Claims (51)

1. An axial retention connection, comprising:

a drill string component including a socket having a plurality of walls and a top surface;

a downhole tool coupled to the socket, the downhole tool including a male-type connector having an outer perimeter and a top surface;

a seal between the drill string component and the downhole tool;

a chamber formed by the plurality of walls and the top surface of the socket and the top surface of the male-type connector; and

a non-compressible fluid filling the chamber such that the hydraulic effect of the non-compressible fluid in the chamber couples the drill string component and the downhole tool and limits axial movement between the drill string component and the downhole tool to less than a length of the male-type connector.

2. The axial retention connection of claim 1 , further comprising:

the drill string component further including

a first pathway extending from a first exterior side of the drill string component to a wall of the socket and including a first funnel; and

a second pathway extending from a second exterior side of the drill string component to a top of the socket and including a second funnel;

a first cap configured to seal a first funnel;

a second cap configured to seal a second funnel; and

the fluid further filling the first pathway and the second pathway.

3. The axial retention connection of claim 2 , wherein at least one of the first cap and the second cap further include a seal.

4. The axial retention connection of claim 2 , wherein the first exterior side and the second exterior side are on the same side of the drill string component.

5. The axial retention connection of claim 1 , wherein the male-type connector and the socket have a compatible shape and are configured to prevent rotation of the male-type connector relative to the socket.

6. The axial retention connection of claim 5 , wherein the compatible shape is a polygon.

7. The axial retention connection of claim 1 , wherein the seal is an O-ring.

8. The axial retention connection of claim 1 , wherein the fluid is a hydraulic fluid.

9. The axial retention connection of claim 1 , wherein the size of the chamber is based on an expected axial expansion of the fluid during a subterranean operation.

10. The axial retention connection of claim 1 , wherein the fluid is selected based on a volumetric expansion coefficient of the fluid.

11. The axial retention connection of claim 1 , further comprising:

a channel passing through the drill string component and the downhole tool;

a second seal located along the channel uphole of the chamber; and

a third seal located along the channel downhole of the chamber.

12. A drilling system, comprising:

a drill string;

a drill string component coupled to the drill string including a socket having a wall and a top surface;

a downhole tool coupled to the socket to create a chamber, the downhole tool including a male-type connector having a wall and a top surface;

a seal between the drill string component and the downhole tool;

the chamber formed by the wall and the top surface of the socket and the top surface of the male-type connector; and

a non-compressible fluid filling the chamber such that the hydraulic effect of the non-compressible fluid in the chamber couples the drill string component and the downhole tool and limits axial movement between the drill string component and the downhole tool to less than a length of the male-type connector.

13. The drilling system of claim 12 , further comprising:

the drill string component further including

a first pathway extending from a first exterior side of the drill string component to a wall of the socket and including a first funnel; and

a second pathway extending from a second exterior side of the drill string component to a top of the socket and including a second funnel;

a first cap configured to seal a first funnel;

a second cap configured to seal a second funnel; and

the fluid further filling the first pathway and the second pathway.

14. The drilling system of claim 13 , wherein at least one of the first cap and the second cap further include a seal.

15. The drilling system of claim 12 , wherein the male-type connector and the socket have a compatible shape and are configured to prevent rotation of the male-type connector relative to the socket.

16. The drilling system of claim 12 , wherein the fluid is a hydraulic fluid.

17. The drilling system of claim 12 , wherein the size of the chamber is based on an expected axial expansion of the fluid during a subterranean operation.

18. A method for coupling a downhole tool, comprising:

partially inserting a downhole tool into a socket on a drill string component;

filling a chamber between the downhole tool and the drill string component with a non-compressible fluid through at least one of a first funnel and a second funnel, the hydraulic effect of the non-compressible fluid in the chamber coupling the drill string component and the downhole tool and limiting axial movement between the drill string component and the downhole tool to less than a length of a male-type connector on the downhole tool, the first funnel coupled to a first pathway and the second funnel coupled to a second pathway, the first and second pathways fluidically coupling the first and second funnels and the chamber;

placing a first cap over the first funnel;

fully inserting the downhole tool into the socket; and

placing a second cap over the second funnel.

19. The method of claim 18 , wherein the fluid is a hydraulic fluid.

20. The method of claim 18 , wherein the size of the chamber is based on an expected axial expansion of the fluid during a subterranean operation.
