Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wellhead systems require multiple reels for different conduits with varying diameters, complicating transportation, storage, and insertion into wellbores, as they need to adjust guide arches and use separate assemblies for each conduit size.

Innovation Solution

A split reel assembly with a splitter flange that separates the drum core into two partitions, allowing for the winding and storage of two conduits of different sizes on the same reel, enabling easy switching between them without needing to adjust the guide arch, and using a levelwind system to control the unwinding and winding of conduits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple reels are used for different conduits, then each conduit can be stored and handled separately, but transportation and storage become complicated and require multiple assemblies

Engineering Contradiction:

Improveability to handle different conduit sizesVSAvoidnumber of reel assemblies required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple conduit storage capacities into a single reel assembly by dividing the drum core into multiple partitions. Each partition can independently store different conduits, allowing the system to handle multiple conduit sizes with one unified assembly rather than requiring separate reels for each conduit type.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The reel assembly is designed with universal functionality to accommodate different conduit sizes through its partitioned structure. The same reel can be used to store and deploy various conduit diameters by selecting the appropriate partition, making the equipment multi-functional and adaptable to different wellhead requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If multiple reels are used for different conduit sizes, then each conduit can be stored properly, but adjustment of guide arches is required for each conduit

Engineering Contradiction:

Improveconduit storage organizationVSAvoidguide arch adjustment requirement

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The drum core is segmented into multiple partitions, with each partition designed to accommodate specific conduit sizes. This segmentation allows proper organization and storage of different conduits while maintaining consistent discharge characteristics, eliminating the need for guide arch adjustments when switching between conduit sizes.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If separate reel assemblies are used for each conduit, then conduit-specific handling is achieved, but transportation and storage space increase

Engineering Contradiction:

Improveconduit handling specializationVSAvoidstorage space for reel assemblies

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The patent merges the functionality of multiple separate reel assemblies into a single integrated unit. By combining multiple conduit storage capacities in one reel with partitioned drum core, the system reduces the total number of reel assemblies needed on-site, thereby decreasing transportation requirements and storage space occupation.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A reel assembly is provided. The reel assembly includes a housing, a drum core disposed within the housing, and a splitter flange separating the drum core into a first partition and a second partition. A first conduit is wound on the first partition of the drum core, and a second conduit is wound on the second partition of the drum core. A conduit handler system is utilized to make a connection or test a connection between the first conduit and the second conduit using actuating pistons to apply a compressive or an opposing tensile force on the connection.
