Amorphous Shaped Charge Liner for Deep Well Perforation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaped charges used for perforating wells face limitations in penetration depth due to solid metal liners, which often leave behind a slug, and crystalline powder liners lack the necessary stretch and effectiveness for deep penetration.
Innovation Solution
A shaped charge with an amorphous-based material liner, tailored to enhance jet stretch and penetration, is used, where the liner and other components are formed through three-dimensional printing to optimize jet formation and minimize debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a solid metal liner is used, then penetration depth is improved, but a slug is left behind blocking the perforation
Solution Approach 1:
The patent changes the material state parameter from solid to amorphous material, which fundamentally alters the liner's behavior during detonation. The amorphous material maintains coherence like solid material for deep penetration but disintegrates cleanly without forming slugs, resolving the contradiction between penetration depth and slug formation.
Solution Approach 2:
The invention uses composite amorphous materials that combine properties of both solid and powder materials. These materials exhibit stretch and coherence similar to solid liners for deep penetration while also having the disintegration characteristics of powder liners to avoid slug formation, effectively merging the benefits of both approaches.
2Object-generated harmful factors
If a crystalline powder liner is used, then slug formation is reduced, but jet stretch and penetration effectiveness are insufficient
Solution Approach 1:
The patent changes the material structure parameter from crystalline to amorphous, which fundamentally alters the material's response to detonation. The amorphous structure provides the necessary coherence and stretch for effective jet formation while maintaining the clean disintegration that prevents slug formation.
Solution Approach 2:
The invention employs composite amorphous materials that integrate the stretch characteristics needed for strong jet formation with the disintegration properties that prevent slug formation, combining the advantages of both solid and powder liners.
3Adaptability or versatility
If three-dimensional printing is used to form the liner, then manufacturing flexibility and jet optimization are improved, but manufacturing complexity increases
Solution Approach 1:
The patent replaces traditional mechanical manufacturing methods (machining, molding) with three-dimensional printing technology. This substitution enables complex geometries and material property gradients to be directly fabricated, optimizing jet formation while the additive nature of 3D printing actually simplifies the manufacturing process for complex shapes.
Solution Approach 2:
The invention utilizes 3D printing to precisely control material distribution, density, and composition parameters within the liner, enabling optimization of jet formation characteristics. The digital design and additive manufacturing process allow for precise parameter control without the complexity of traditional multi-step manufacturing.
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
The amorphous-based material liner achieves deeper and more effective perforations by maintaining coherence and reducing the formation of blocking debris, allowing for enhanced hydrocarbon recovery without occlusive slugs.
Implementation Method 1
The jet formed by the detonation of a given shaped charge may pierce steel casing, cement and a variety of different types of rock that make up the surrounding formation
Implementation Method 2
detonation of the explosive within the case may be utilized to direct the liner away from the gun and toward the well wall as a means by which to form the noted jet

AI summary
An amorphous-based material component may be incorporated into a liner for a shaped charge used in perforating a wellbore casing. Other components of the shaped charge and/or perforating gun that accommodates the shaped charge may be of amorphous-based materials. Further, the liner and other components of the shaped charge may be manufactured by way of three dimensional printing. Indeed, a multi-material three dimensional print application may be utilized to form shaped charge components simultaneously along with an entire perforating gun system.
