Contraction Joint Communication Line Organizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of contraction joints in well completions often leads to tangling and binding of multiple communication lines, causing deformation and catastrophic failure due to non-uniform contraction and extension, especially when multiple lines are involved.
Innovation Solution
A communication line organizer system is positioned along the contraction joint to prevent tangling and binding, allowing for smooth movement and expansion by using a combination of line organizer members and a shroud to manage and support the communication lines, ensuring they do not bind or deform during contraction and expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication lines are routed along the contraction joint, then communication capability is improved, but the lines become tangled and bound during operation
Solution Approach 1:
The communication lines are segmented into individual channels within the communication line organizer, with each line having its own designated path. This segmentation prevents the lines from interacting and tangling with each other during contraction joint operation, while still allowing multiple lines to be routed along the joint for improved communication capability.
Solution Approach 2:
The communication line organizer acts as an intermediary device between the multiple communication lines and the contraction joint. It provides a structured framework that guides and separates the lines, preventing them from becoming tangled or bound against portions of the contraction joint during operation.
2Ease of operation
If communication lines are wrapped around the contraction joint, then the joint can contract and extend freely, but the lines become deformed and stretched beyond material limits
Solution Approach 1:
The communication line organizer employs flexible structures including flexible members and a shroud that can accommodate the contraction and extension movements of the joint. These flexible elements guide the communication lines through the movement range without allowing them to wrap tightly around the joint, preventing deformation and stretching beyond material limits while maintaining joint mobility.
Solution Approach 2:
The communication line organizer is designed with dynamic characteristics that allow it to adapt to the changing geometry of the contraction joint during operation. The flexible members and shroud can move and deform within acceptable limits to accommodate joint contraction and extension, while maintaining proper line alignment and preventing excessive stress on the communication lines.
3Reliability
If a single communication line is wrapped around the contraction joint, then the line maintains integrity during movement, but multiple lines become tangled with each other
Solution Approach 1:
The communication line organizer segments multiple communication lines into separate, organized channels. Each line is individually guided through the contraction joint region, maintaining the integrity benefits of individual routing while preventing the tangling complexity that would result from multiple lines moving independently.
Solution Approach 2:
The communication line organizer merges the routing functions for multiple communication lines into a single integrated structure. This combining approach maintains the reliability benefits of individual line protection while reducing the overall complexity of managing multiple separate line routing systems.
