Axial Grooves for Cable Routing in Tubing Anchoring Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tubing anchoring tools face difficulties in accommodating cables due to limited annular space between the tubing string and wellbore casing, especially in smaller diameters, and existing tools require multiple rotations or are not adaptable for narrow well conduits, leading to issues with cable management and functionality.
Innovation Solution
Incorporating axial grooves along the slip cage and drag body of tubing anchoring tools, allowing cables to be placed within these grooves, which are designed to accommodate cables while maintaining the structural integrity of the tools, even in quarter turn or multi-rotation settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are run along tubing strings past tubing anchoring tools, then cable management is required, but there is very little annular space between the tubing string and wellbore casing making it difficult
Solution Approach 1:
The patent introduces axial grooves on the outer surface of the anchoring tool body, transitioning cable routing from the limited annular space to the external surface dimension. This allows cables to be guided along the tool's length without occupying precious annular space between tubing and casing.
Solution Approach 2:
The axial grooves act as intermediary structures that receive and guide cables. These grooves provide a dedicated pathway for cable routing, mediating between the cable and the anchoring tool while preventing cable interference with internal components like slips and drag blocks.
2Ease of operation
If axial grooves are added to accommodate cables, then cable management improves, but the structural integrity of the tool may be compromised
Solution Approach 1:
The axial grooves are positioned specifically on the outer surface of the anchoring tool body where they provide cable routing functionality without interfering with the load-bearing internal structure. This localized modification maintains structural integrity while adding cable accommodation capability.
