Adapter Assembly for Outer Barrel Bowl Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In well drilling, the need for multiple sizes of outer barrels and bowls increases equipment costs and complexity, as different sized barrels are required for secure attachment to various sized bowls, leading to inefficiencies in drilling operations.
Innovation Solution
An adapter assembly that increases the exterior size of the outer barrel or nipple base, allowing it to be attached to different sized bowls, reducing the need for multiple barrel sizes and simplifying the attachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different sized outer barrels are used for different sized bowls, then secure attachment is achieved, but equipment costs and complexity increase
Solution Approach 1:
The adapter assembly enables a single outer barrel to be used with multiple different sized bowls by providing an intermediate connection interface. The adapter has an inner portion that attaches to the outer barrel and an outer portion that attaches to the bowl, allowing one outer barrel to serve multiple bowl sizes (16-inch, 20-inch, 24-inch, 30-inch) thereby reducing equipment variety while maintaining secure attachment.
2Adaptability or versatility
If multiple sized outer barrels are maintained, then compatibility with various bowls is ensured, but equipment costs increase
Solution Approach 1:
The adapter assembly is divided into an inner portion and an outer portion that can be separately attached to the outer barrel. This segmentation allows the adapter to be configured for different bowl sizes while using a single outer barrel, reducing the total quantity of equipment needed while maintaining adaptability across various bowl sizes.
3Reliability
If different sized outer barrels are used, then proper fit for each bowl size is achieved, but operational efficiency decreases
Solution Approach 1:
The adapter assembly serves as an intermediary component between the outer barrel and the bowl. Instead of requiring different outer barrels for each bowl size, the adapter mediates the connection by providing the appropriate interface geometry for each bowl size while attaching to a standard outer barrel, thereby improving operational efficiency while maintaining proper fit.

AI summary
The adapter assembly extends outward from an inner structure such as an outer barrel or nipple base to attach the inner structure to a housing such as a bowl. Each sized inner structure fits a specified bowl for attachment of the inner structure to the bowl. The adapter assembly extends outward from the inner structure to fit one of the available sizes needed for attachment to the bowl. The adapter assembly is characterized by a first attachment body and a second attachment body. The adapter assembly attaches to the exterior of the inner structure to increase the surface exterior of the outer surface for attachment of the inner structure to the bowl.
