Solution Overview

Problem

Existing wired pipe configurations in the drilling and completion industry face challenges in efficiently transmitting power and communication signals due to obstacles such as protective steel tubings that hinder fluid flow and require complex manufacturing processes, while existing solutions for embedding conductors like wires or optical fibers within pipes do not adequately address the need for efficient signal transmission and structural integrity.

Innovation Solution

A tubular pipe body with a metal material and integrated helical wire channels formed during extrusion, allowing for the direct embedding of transmission lines like electrical conductors or optical fibers, which have a melting temperature equal to or greater than the pipe material, ensuring structural integrity and efficient signal transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protective steel tubings are used to protect conductors, then conductor protection is improved, but fluid flow efficiency deteriorates

Engineering Contradiction:
Improveconductor protectionVSAvoidfluid flow efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent removes the separate protective tubing from the system by integrating conductor protection directly into the pipe wall structure. Conductors are embedded within channels formed in the pipe wall itself, eliminating the need for additional protective tubings that would obstruct fluid flow.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the functions of structural support, fluid conveyance, and conductor protection into a single integrated pipe structure. The channels for conducting signals are formed directly within the pipe wall, merging previously separate functions into one unified component.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If complex manufacturing processes are used to embed conductors, then conductor embedding capability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveconductor embedding capabilityVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent incorporates conductor channels into the pipe structure during the initial extrusion or forming process, before the pipe is assembled or installed. This preliminary integration of channels simplifies subsequent manufacturing steps and eliminates the need for complex post-processing to embed conductors.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pipe structure is designed to serve multiple functions simultaneously: structural support, fluid conveyance, and signal transmission. The integrated channels allow the same pipe structure to handle both hydraulic flow and electrical/optical signals, reducing the need for separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If transmission lines are embedded during extrusion, then manufacturing complexity is reduced, but transmission line temperature resistance requirement increases

Engineering Contradiction:
Improvemanufacturing process complexityVSAvoidtransmission line temperature resistance
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

The patent specifies that transmission lines must have melting temperatures substantially equal to or greater than the pipe material's melting temperature. This parameter requirement ensures that conductors can withstand the high temperatures of the extrusion process without deforming or failing, enabling direct embedding during manufacturing.

Inventive Principle:
Principle #35Parameter changes
