Abstract

An anchoring assembly in a downhole tool, the assembly including a first tubular member, a second tubular member coupled to the first tubular member, and an anchoring block disposed between the first tubular member and the second tubular member. The anchoring block includes a body having a central axis defined therethrough and a central bore formed therethrough, a contact crown, in which at least one annular flow channel is formed between the contact crown and the body, and a contact ring configured to engage at least a portion of the first tubular member.

First claim

What is claimed is:

1. An anchoring assembly, the assembly comprising:
a first tubular member;
a second tubular member coupled to the first tubular member; and
an anchoring block disposed between the first tubular member and the second tubular member, the anchoring block comprising:
a body having a central axis defined therethrough and a central bore formed therethrough;
a contact crown, wherein at least one annular flow channel is formed between the contact crown and the body;
a contact ring configured to engage at least a portion of the first tubular member; and
at least one biasing member disposed between the contact ring and the contact crown, wherein the at least one biasing member is configured to exert force on the contact ring and on the contact crown and securely engage the anchoring block between the first tubular member and the second tubular member.

2. The assembly of claim 1 , wherein the central bore of the body of the anchoring block is configured to receive at least one tool.

3. The assembly of claim 2 , the anchoring block further comprising an alignment member formed on an inner surface of the central bore of the body, wherein the alignment member is configured to align the at least one tool disposed within the central bore of the body of the anchoring block.

4. The assembly of claim 1 , the anchoring block further comprising a lock pin, wherein the lock pin is disposed in the contact crown of the anchoring block in a direction that is parallel to the central axis of the anchoring block.

5. The assembly of claim 1 , wherein a lower portion of the contact crown of the anchoring block comprises a tapered portion, wherein the tapered portion of the contact crown is configured to engage at least a portion of the second tubular member.

6. The assembly of claim 1 , wherein at least one connection wing extends radially between the body and the contact crown of the anchoring block.

7. An anchoring block, the block comprising:
a body having a central axis defined therethrough and a central bore formed therethrough;
a contact crown, wherein at least one annular flow channel is formed between the contact crown and the body;
a contact ring configured to engage at least a portion of a first tubular member; and
at least one biasing member disposed between the contact ring and the contact crown, wherein the at least one biasing member is configured to exert force on the contact ring and securely engage the first tubular member.

8. The anchoring block of claim 7 , wherein the central bore is configured to receive at least one tool.

9. The anchoring block of claim 8 , further comprising an alignment member formed on an inner surface of the central bore of the body, wherein the alignment member is configured to align the at least one tool disposed within the central bore of the body.

10. The anchoring block of claim 7 , further comprising a lock pin, wherein the lock pin is disposed in the contact crown in a direction that is parallel to the central axis of the anchoring block.

11. The anchoring block of claim 7 , wherein a lower portion of the contact crown comprises a tapered portion.
