Wellbore Cable Clamp Layout for Sensor and Splice Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamps for holding cables in wellbores struggle with splices or sensors that are larger than the cable size or sensitive to clamping loads, leading to damage and inefficiencies in downhole operations.
Innovation Solution
A modular t-slot clamp design with multiple slots along the channel allows for easy relocation to avoid clamping over sensors or splices, providing secure cable support without damaging sensitive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamp is used to hold cables in position, then cable support and positioning are improved, but sensors or splices on the cables may be damaged due to clamping loads
Solution Approach 1:
The clamp is designed with a movable position along the channel, allowing it to be dynamically repositioned to avoid clamping on sensors or splices. The channel includes multiple positioning locations, enabling the clamp to adapt its position based on the cable configuration and sensitive component locations, thus maintaining reliable cable support while avoiding damage to sensitive elements.
2Ease of manufacture
If the clamp position is fixed, then installation simplicity is improved, but the clamp cannot avoid sensors or splices when they are larger than cable size
Solution Approach 1:
The channel is segmented into multiple discrete positioning locations, allowing the clamp to be installed at different positions along the channel. This segmentation enables the system to adapt to varying cable configurations and sensor locations while maintaining relatively simple installation procedures, as the clamp can be positioned at predetermined locations without complex adjustments.
3Object-affected harmful factors
If the clamp is relocated to avoid sensors, then damage to sensitive components is reduced, but device complexity increases due to multiple slots and relocation mechanism
Solution Approach 1:
The clamp incorporates a movable mechanism that allows it to shift between multiple positioned locations along the channel. This dynamic capability enables the clamp to relocate away from sensors or splices when needed, reducing the risk of damage while maintaining a relatively simple overall structure through standardized components and predictable movement patterns.

AI summary
A tubing to be positioned in a wellbore, the tubing comprising: a channel having multiple pairs of slots created on each side of the channel, wherein each of the multiple pairs of slots is positioned at different depths of the wellbore, wherein at least one cable is to be positioned in the channel and comprises at least one of a sensor or a splice; and a clamp configured to be positioned in each of the multiple pairs of slots and configurable to clamp down on the at least one cable positioned in the channel, wherein the clamp is to be positioned in a first pair of slots of the multiple pairs of the slots such that clamp is not positioned over the at least one sensor or the splice of the least one cable.
