Abstract

An electronic frame for use in a downhole component coupling mechanism includes: a first frame element including at least one retaining structure configured to retain an electronic component; and a second frame element configured to be disposed at the first frame element, the second frame element permanently joined to the first frame element to isolate the electronic component from downhole fluids and form the electronic frame, the electronic frame configured to be disposed in a coupling assembly of a first downhole component and a second downhole component and constrained axially by the coupling assembly.

First claim

What is claimed is:

1. An electronic frame for use in a downhole component coupling mechanism, comprising:
a first frame element including at least one retaining structure configured to retain an electronic component, the electronic component including signal coupling elements that transmit signals between a first downhole component and a second downhole component; and
a second frame element attached to the first frame element to form the electronic frame, encapsulate the electronic component within the electronic frame and isolate the electronic component from downhole fluids, the second frame element attached to the first frame element by a permanent and fluid-tight mechanical joining, the second frame element in a fixed rotational relationship relative to the first frame element, the electronic frame being separate and removable from a coupling assembly of the first downhole component and the second downhole component, the electronic frame configured to be encapsulated within a space formed by the coupling assembly of the first downhole component and the second downhole component, and the electronic frame having a shape that conforms to the space formed by the coupling assembly to cause the electronic frame to be constrained by the coupling assembly, wherein the coupling assembly is configured to communicatively connect the first downhole component to the second downhole component via the electronic frame.

2. The electronic frame of claim 1 , further comprising a fluid conduit formed by at least one of the first frame element and the second frame element, the fluid conduit configured to provide fluid communication through the coupling assembly and between the first and second downhole component.

3. The electronic frame of claim 1 , wherein the coupling assembly further includes a pin located at an end of the first downhole component and a box at an end of the second downhole component.

4. The electronic frame of claim 3 , wherein the electronic frame is further configured to be disposed in a bore-back region of the box and constrained axially by the pin and the box when the downhole component coupling mechanism is assembled, the bore-back region provided to reduce stress concentrations due to loads on the coupling assembly.

5. The electronic frame of claim 1 , wherein the second frame element is welded to the first frame element to provide a fluid-tight seal between the first frame element and the second frame element.

6. The electronic frame of claim 1 , wherein the electronic frame is further configured to be encapsulated in the space formed by the coupling assembly without any rotationally securing feature.

7. The electronic frame of claim 6 , wherein the at least one retaining structure includes at least one recess formed in a surface of the first frame element, and the second frame element includes at least one of a sleeve and a cover configured to surround at least a portion of the surface on which the at least one recess is formed.

8. The electronic frame of claim 1 , wherein the second frame element includes a plurality of separate frame elements permanently joined to the first frame element.

9. The electronic frame of claim 8 , wherein the at least one retaining structure includes at least one recess, the at least one recess includes at least one first recess that retains the electronic component and at least one second recess that retains a redundant electronic component, one of the plurality of separate frame elements configured to cover the first recess and another of the plurality of separate frame elements configured to cover the second recess.

10. The electronic frame of claim 1 , wherein the electronic frame further includes at least one recess formed between the first frame element and the second frame element, and the electronic frame is a cylindrical structure formed by the first frame element and the second frame element, the cylindrical structure having an inner surface forming a fluid conduit that provides fluid communication between the first downhole component and the second downhole component, and an outer surface conforming to the space formed by the coupling assembly.

11. A method of coupling downhole components comprising:
disposing an electronic component in at least one retaining structure of a first frame element of an electronic frame, the electronic component including signal coupling elements that transmit signals between a first downhole component and a second downhole component;
attaching a second frame element to the first frame element by a permanent and fluid-tight mechanical joining to form the electronic frame, encapsulate the electronic component within the electronic frame and isolate the electronic component from downhole fluids, the second frame element in a fixed rotational relationship relative to the first frame element;
disposing the electronic frame in a coupling assembly of the first downhole component and the second downhole component, the electronic frame being separate and removable from the coupling assembly; and
coupling the first downhole component to the second downhole component, wherein said coupling the first downhole component to the second downhole component includes encapsulating the electronic frame within a space formed by the coupling assembly and constraining the electronic frame by the coupling assembly, wherein said coupling the first downhole component to the second downhole component further includes communicatively connecting the first downhole component to the second downhole component via the electronic frame.

12. The method of claim 11 , further comprising disposing the first downhole component and the second downhole component in a borehole in an earth formation and performing a downhole operation, the downhole operation including advancing a borehole fluid between the first downhole component and the second downhole component through a fluid conduit formed by at least one of the first frame element and the second frame element.

13. The method of claim 11 , wherein said coupling the first downhole component to the second downhole component further includes encapsulating the electronic frame without rotationally securing the electronic frame.

14. The method of claim 11 , wherein the coupling assembly includes a pin located at an end of the first downhole component and a box at an end of the second downhole component.

15. The method of claim 14 , wherein disposing the electronic frame in the coupling assembly further includes disposing the electronic frame in a bore-back region of the box, the bore-back region provided to reduce stress concentrations due to loads on the coupling assembly.

16. The method of claim 11 , wherein the at least one retaining structure includes at least one recess formed in a surface of the first frame element.

17. The method of claim 16 , wherein the second frame element includes at least one of a sleeve and a cover configured to surround at least a portion of the surface on which the at least one recess is formed.

18. The method of claim 11 , wherein the second frame element includes a plurality of separate frame elements permanently joined to the first frame element.

19. The method of claim 18 , wherein the at least one retaining structure includes at least one recess, the at least one recess includes at least one first recess that retains the electronic component and at least one second recess that retains a redundant electronic component, one of the plurality of separate frame elements configured to cover the first recess and another of the plu
