Pocket for a downhole tool string component
View Patent ↗A downhole tool string component, having a tubular body with an outer diameter. A first, second, and third flange are disposed around the outer diameter of the tubular body at different axial locations. A first sleeve is disposed around the tubular body such that opposite ends of the first sleeve fit around at least a portion of the first and second flanges, forming a first sealed pocket around the outer diameter of the tubular body. A second sleeve is disposed around the tubular body such that opposite ends of the second sleeve fit around at least a portion of the second and third flanges, forming a second sealed pocket around the outer diameter of the tubular body.
1. A downhole tool string component, comprising:
a tubular body with an outer diameter;
a first, second, and third flange are disposed around the outer diameter of the tubular body at different axial locations;
a first sleeve disposed around the tubular body such that opposite ends of the first sleeve connect to at least a portion of the first and second flanges;
a second sleeve disposed around the tubular body such that opposite ends of the second sleeve connect to at least a portion of the second and third flanges; and
at least one sleeve forming a pocket around the outer diameter of the tubular body;
wherein an end of at least one sleeve fits around a portion of at least one flange.
2. The component of claim 1 , wherein the first pocket is electrically connected to a second pocket formed around the outer diameter of the tubular body by the second sleeve.
3. The component of claim 2 , wherein the pockets are electrically connected through an electrically conductive conduit disposed within the second flange.
4. The component of claim 1 , wherein at least one flange and at least one sleeve are a single element.
5. The component of claim 1 , wherein the first and second sleeves are interlocked.
6. The component of claim 5 , wherein the sleeves are interlocked with a castle cut connection.
7. The component of claim 1 , wherein an electronics housing is disposed within at least one of the pockets.
8. The component of claim 7 , wherein the electronics housing is interlocked with at least one flange.
9. The component of claim 7 , wherein the electronics housing is interlocked with the tubular body.
10. The component of claim 1 , wherein at least one pocket is sealed.
11. The component of claim 1 , wherein the flanges comprise o-rings disposed along an outer diameter of the flanges.
12. The component of claim 1 , wherein the flanges comprise o-rings disposed along an inner diameter of the flanges.
13. The component of claim 1 , wherein the component also comprises a collar disposed around the tubular body at an end and adapted to be a primary shoulder of the component.
14. The component of claim 1 , wherein at least one sleeve is a stabilizer adapted to stabilize the component in a well bore.
15. The component of claim 1 , wherein the first sleeve abuts a shoulder formed in the outer diameter of the downhole component.
16. The component of claim 1 , wherein at least one sleeve is made of a non-magnetic material.
17. The component of claim 1 , wherein the component comprises a third sleeve disposed around the tubular body such that opposite ends of the third sleeve connect to at least a portion of the third flange and a fourth flange, forming another pocket around the outer diameter of the tubular body.
