Screen Jacket Termination Using Welded Strip Between Wire Wraps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sand screen termination methods require significant manpower and costly processes to ensure the wire stays in place, leading to inefficiencies in resource recovery operations.
Innovation Solution
A screen jacket termination configuration that includes a base pipe, ribs, wire wrapping, and a termination strip wrapped between the wire wraps, which is welded to the base pipe and ribs to create a secure and sand-tight end without the need for end rings, ensuring the gap between the termination strip and the base pipe is less than the screen jacket gauge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end rings are used to secure the wire at the termination of the screen jacket, then the wire stays in place reliably, but the process requires significant manpower and costly welding operations
Solution Approach 1:
The patent removes the end ring component from the screen jacket termination system. Instead of using a separate end ring to secure the wire, the termination strip itself performs the securing function through its integrated design with the base pipe and screen jacket, eliminating the need for additional components and welding operations.
Solution Approach 2:
The termination strip combines multiple functions into a single component: it secures the screen jacket to the base pipe, maintains the sand-tight seal, and eliminates the need for separate end rings. This merging of functions reduces complexity and manufacturing costs while improving efficiency.
2Reliability
If end rings are welded in place to ensure wire stability, then the termination is secure, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent eliminates the end ring component and its associated welding operations. The termination strip is designed to work with the base pipe and screen jacket without requiring separate welding steps for end rings, simplifying the manufacturing process while maintaining security.
Solution Approach 2:
The termination strip appears to be a simpler, more economical component compared to welded end rings. The design favors a less complex solution that achieves the same functional outcome without the high costs and complexity of welding operations.
3Ease of manufacture
If the gap between the screen jacket and base pipe is not controlled, then the termination is easier to manufacture, but sand particles larger than the filtered size can enter the filtered volume
Solution Approach 1:
The termination strip is designed to create a localized sand-tight seal at the termination end of the screen jacket. This local quality enhancement ensures that sand particles cannot enter the filtered volume at the ends, while the rest of the screen jacket maintains its standard structure and manufacturing simplicity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the efficiency and cost-effectiveness of sand screen termination by providing a secure and sand-tight seal at the end of the screen jacket, reducing the risk of sand particles larger than the filtered size entering the filtered volume, while eliminating the need for end rings and associated costly processes.
Implementation Method 1
a termination strip wrapped about the base pipe and rib and disposed between wraps of the wire

AI summary
A screen jacket termination configuration includes a base pipe, a rib disposed at the base pipe, a wire wrapped about the base pipe and rib to form a screen jacket, and a termination strip wrapped about the base pipe and rib and disposed between wraps of the wire. A method for terminating a screen jacket includes disposing a termination strip between adjacent wraps of a screen jacket, the termination strip closing a space between the screen jacket and a base pipe at an end of the screen jacket such that any gap between the termination strip and the base pipe is less than a gauge of the screen jacket.
