Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wellbore tool string assembly is time-consuming and labor-intensive, with potential for tool string obstruction due to deformities and the need for efficient and secure connection of components.
Innovation Solution
A connector assembly comprising a receptor assembly and a snap assembly that allows for quick and secure coupling of wellbore tools, including electrical connections, using snap mechanisms and biasing members to facilitate alignment and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional threaded insertion methods are used to assemble wellbore tools, then the connection is secure and reliable, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The connector is divided into separate components: a receptor assembly with a receptor groove and a snap assembly with protruding snaps. This segmentation allows for quick connection by simply engaging the snaps into the groove, eliminating the need for time-consuming threaded insertion while maintaining secure connection through the interlocking geometry of the snaps and groove.
2Productivity
If quick-connect mechanisms are used to speed up assembly, then assembly time is reduced, but the connection may not be as secure or reliable
Solution Approach 1:
The snaps are designed with curved, arc-shaped engagement surfaces that conform to the receptor groove geometry. This curvature allows the snaps to flex during engagement and then lock securely into place, providing both quick connection and reliable, secure attachment that can withstand the forces encountered in wellbore operations.
Solution Approach 2:
The connection mechanism transitions from one-dimensional linear threading to two-dimensional angular engagement. The snaps engage with the receptor groove at specific angles and positions, creating a multi-point interlocking connection that provides both speed and reliability. The geometric constraints in multiple dimensions ensure secure attachment while allowing rapid assembly.
3Adaptability or versatility
If multiple components are assembled together to create a complete tool string, then the tool string becomes more functional and versatile, but the complexity of assembly increases
Solution Approach 1:
The connector design with standardized receptor grooves and matching snaps can be used to join various types of wellbore tools including perforating guns, setting tools, and other downhole equipment. This universal interface allows different functional components to be easily assembled into complete tool strings without requiring complex or tool-specific connection procedures, thereby simplifying assembly while maintaining versatility.
