Rotatable Downhole Tool Support Stand for Safe Threading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual installation of downhole tools onto well tubulars is cumbersome and hazardous due to the weight and size of the tools, posing risks such as back strain, finger pinching, and exposure to hazardous materials during the threading process.
Innovation Solution
A support stand with a rotatable downhole tool seat mounted on a structural frame, allowing for secure positioning and rotation of the tool relative to the tubular, facilitated by ground-engaging members, jacking mechanisms, and tilting capabilities to align and thread the tool safely and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual installation methods are used to install downhole tools onto well tubulars, then the installation process can be performed with simple equipment, but the operation becomes cumbersome and hazardous due to the weight and size of the tools
Solution Approach 1:
The patent introduces a support stand with a rotatable seat as an intermediary device between the worker and the downhole tool. The seat supports the heavy tool during installation, allowing workers to operate it safely without directly handling the full weight. The seat rotates to enable threading the tool onto the tubular while maintaining safe distances from hazardous areas.
2Device complexity
If heavy downhole tools are handled manually, then equipment complexity is minimized, but physical strain and injury risks increase significantly
Solution Approach 1:
The support stand with rotatable seat enables self-service operation where the tool itself is supported and positioned by the device during installation. The seat automatically rotates during the threading process, reducing the need for manual manipulation of heavy components and minimizing physical strain on workers.
3Productivity
If manual threading operations are performed, then the installation process can be completed with basic tools, but exposure to hazardous materials and dangerous positions increases
Solution Approach 1:
The rotatable seat acts as an intermediary that enables efficient threading operations while maintaining a safe working distance. The seat rotates to bring the tool into engagement with the tubular, allowing workers to operate from safer positions and reducing exposure to hazardous materials and dangerous areas near the wellbore.
