Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wired pipe configurations for subterranean drilling and completion operations face challenges in reliable and efficient transmission of power and communication signals due to limitations in coupling mechanisms, particularly in the pin box connection, which can lead to signal interference and reduced connectivity between pipe segments.
Innovation Solution
A wired pipe segment design that includes a coupler with a communication element and a transmission line with an inner conductor surrounded by dielectric material, connected via a hollow connector with an internal connection element that electrically connects the coupler to the transmission line, allowing for secure and efficient signal transmission between pipe segments using a connector that does not completely surround the inner conductor or coupler connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a threaded pin box connection is used to couple pipe segments, then mechanical connection strength is improved, but signal transmission reliability deteriorates due to interference and connectivity issues
Solution Approach 1:
The connector is divided into functionally independent components: a coupling body for mechanical connection and a separate transmission line system for signal transmission. This segmentation allows the mechanical threading to provide strength while the isolated transmission line maintains signal reliability without interference from the mechanical coupling components.
2Object-generated harmful factors
If the inner conductor is completely surrounded by the connector, then electrical shielding is improved, but signal transmission efficiency deteriorates due to increased interference
Solution Approach 1:
The connector provides selective shielding: the coupling body partially surrounds the transmission line to provide mechanical protection and localized electrical shielding where needed, while leaving portions of the inner conductor exposed or accessible. This local quality approach maintains necessary shielding without completely surrounding the conductor, preserving signal transmission efficiency.
3Ease of manufacture
If a traditional coaxial connector design is used, then ease of manufacture is improved, but adaptability to harsh drilling environments deteriorates
Solution Approach 1:
The connector employs composite construction combining conductive materials for electrical connection with non-conductive dielectric materials for insulation and protection. This composite approach provides both the manufacturing simplicity of traditional connectors and the enhanced adaptability needed for harsh drilling environments with vibrations and high forces, as different materials contribute their specific properties to withstand various environmental stresses.

AI summary
A connector for use in connecting a communication element to a transmission line in a wired pipe segment includes a first female end adapted to surround and make electrical contact with a coupler connection that extends away from a communication element of the coupler; a second female end adapted to receive an inner conductor of a coaxial cable; and an inner connection element formed on an inner surface of the connector adapted to electrically connect the coupler connection and the inner conductor, the inner connection element formed such that it does not completely surround at least one of the inner conductor and the coupler connection.
