Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tools for assembling and disposing of oilfield tubulars require frequent tool changes when dealing with tubulars of different diameters, leading to inefficiencies, time delays, increased costs, and safety risks.
Innovation Solution
A tubular running tool featuring a mandrel with radially outwardly actuated slips, each equipped with a swappable insert having a gripping portion, allowing for secure engagement and disengagement with tubulars of varying diameters without the need for tool changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tools designed for specific pipe diameters are used, then the tool can securely grip the pipe, but the tool must be replaced when different diameter pipes are used, causing time delays and increased costs
Solution Approach 1:
The tool is divided into a reusable mandrel and interchangeable inserts. Each insert is designed with a specific gripping portion for a particular pipe diameter, while the mandrel serves as a universal base. This segmentation allows the gripping function to be separated from the structural support, enabling quick swaps of inserts for different pipe sizes without replacing the entire tool.
Solution Approach 2:
The mandrel is designed as a universal component that can accommodate multiple inserts with different gripping portions. This multi-functionality allows a single mandrel to handle various pipe diameters by simply changing the insert, eliminating the need for multiple specialized tools and reducing replacement time.
2Adaptability or versatility
If multiple specialized tools for different pipe diameters are maintained, then each pipe size can be handled effectively, but device complexity and logistics become more difficult
Solution Approach 1:
A single mandrel is designed with a universal interface that accepts multiple inserts for different pipe diameters. This universality reduces the entire toolset from multiple specialized tools to one versatile mandrel with interchangeable inserts, simplifying device complexity while maintaining adaptability to various pipe sizes.
Solution Approach 2:
By separating the gripping function into independent inserts that can be quickly attached to or removed from the mandrel, the system maintains versatility across different pipe diameters without requiring multiple complex tools. The modular design makes the system easier to manage and logistically simpler.
3Device complexity
If conventional tools are used for different pipe diameters, then the tool structure can be simplified for a single diameter, but personnel safety risk increases due to frequent tool changes
Solution Approach 1:
The tool is segmented into a robust mandrel and interchangeable inserts. The mandrel maintains a simple, optimized structure for a single pipe diameter range, while the inserts provide the necessary gripping variations. This segmentation reduces the complexity of the mandrel itself while enabling safe operation across different pipe sizes through quick insert changes without tool replacement.
Solution Approach 2:
The inserts are pre-designed with specific gripping portions optimized for different pipe diameters. By having these inserts ready and pre-configured, personnel can quickly swap inserts rather than tools, reducing the time personnel are exposed to hazardous situations and minimizing safety risks associated with frequent tool changes.

AI summary
A tubular running tool equipped with a mandrel having an elongated body and configured for suspension above a wellbore. A plurality of slips are disposed on the mandrel. Each slip is configured to receive and hold a swappable insert via a releasable interlocking junction. Each swappable insert is configured with a gripping portion on an outer surface thereof. The mandrel is configured for actuation to urge the slips radially outward such that the swappable inserts disposed thereon are correspondingly urged radially outward. A method and system using the tool for running a tubular and providing a makeup torque.
