Abstract

A drilling system includes a first section of a drilling tool having a collar configured to hold internal components of the first section. The drilling system also includes a second section of the drilling tool configured to be coupled with the first section in a specific orientation relative to the first section. The second section is interchangeable with at least one different section.

First claim

What is claimed is:

1. A drilling system, comprising:
a first section of a drilling tool having a transition block disposed in a collar configured to hold internal components of the first section; and
a second section of the drilling tool having an inner portion and a collar portion of a solid block, wherein the collar is configured to rotatably couple with the collar portion, wherein the transition block is configured to be coupled with the inner portion in a specific, non-rotatable, orientation relative to the inner portion, and
wherein the second section is interchangeable with at least one different section.

2. The drilling system of claim 1 , wherein the drilling tool comprises a probe module, the first section comprises a utility section, and the second section comprises a probe section.

3. The drilling system of claim 2 , wherein the utility section is configured to provide hydraulic power for extending a probe of the probe section.

4. The drilling system of claim 2 , comprising a pump out module configured to direct formation fluid through the drilling tool to sample carrier module comprising sample bottles storing formation fluid.

5. The drilling system of claim 2 , wherein the probe section is interchangeable with a plurality of different probe sections, each different probe section having a different type of probe or a different type of setting apparatus.

6. The drilling system of claim 1 , wherein the transition block comprises:
two fluid connections to direct hydraulic fluid and sampling fluid between the first and second sections;
a multi-pin electrical connection to direct power flow between the first and second sections; and
an asymmetric indexing feature configured to be received through a corresponding hole of the inner portion.

7. The drilling system of claim 1
wherein the collar portion is disposed around the inner portion.

8. A drilling system, comprising:
a transition block configured to couple a first section and a second section of a drilling tool, the second section being interchangeable with one or more different sections of the drilling tool;
wherein the transition block is configured to couple with an inner portion of the second section in a specific fixed relative orientation, and the transition block is configured to be disposed in a collar of the first section without regard to an orientation of the transition block relative to the collar such that the collar can be rotatably coupled with a collar portion of the second section.

9. The drilling system of claim 8 , wherein the drilling tool comprises a probe module and the transition block is configured to couple a utility section of the probe module with a probe section of the probe module, the probe section having an extendable probe.

10. The drilling system of claim 9 , wherein the transition block comprises at least two fluid connections and an electrical connection to direct hydraulic fluid, sampling fluid, and electricity between the utility section and the probe section.

11. The drilling system of claim 8 , wherein the transition block comprises an indexing feature for receiving torsional loads between the transition block and the inner portion.

12. The drilling system of claim 11 , wherein the indexing feature comprises an asymmetric key.

13. The drilling system of claim 8 , wherein the transition block allows passage of drilling fluid between the first and second sections.

14. A method of manufacturing a drilling tool, comprising:
attaching a transition block of a first section of the drilling tool to an inner portion of a second section of the drilling tool in a specific, non-rotatable, orientation relative to the inner portion;
disposing the transition block within a collar of the first section; and
attaching the collar to a collar portion of the second section without regard to an orientation of the collar relative to the collar portion.

15. The method of claim 14 , comprising:
sliding the transition block into the collar;
threading a first end of the collar onto the collar portion;
inserting a spring pack into the collar; and
threading a saver sub onto a second end of the collar.

16. The method of claim 14 , comprising interchanging the second section with a different section of the drilling tool.

17. The drilling system of claim 1 wherein the second section comprises:
a probe extending from the solid block; and
one or more drilling fluid channels extending within the second section between the inner portion and the collar portion.

18. The drilling system of claim 8 , comprising the first and second sections of the drilling tool each coupled to the transition block, wherein the second section comprises a solid block forming the inner portion coupled to the transition block and the collar portion coupled to the collar of the first section.

19. The method of claim 14 wherein the second section comprises a solid block forming the inner portion and the collar portion, and wherein attaching the transition block to the inner portion comprises coupling an indexing feature of the transition block to a corresponding hole in the inner portion of the solid block.
