Modular Boost System for Well Jack Lifting Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Well tools often become stuck in subterranean formations, and existing jacks lack sufficient lift capabilities to dislodge them, necessitating the need for increased lifting forces during well operations.
Innovation Solution
A modular boost system is introduced, which includes additional boost cylinders that can be removably coupled to a jack, providing supplementary lift force by acting between an adjustable plate and the base plate, enhancing the jack's lifting capacity when combined with its built-in hydraulic cylinders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If additional lift capability is needed to dislodge stuck well tools, then lifting force is improved, but device complexity increases
Solution Approach 1:
The jack system is divided into a base jack unit and a separate modular boost system. The boost system includes its own boost cylinder, adjustable plate, and coupling mechanisms that can be independently attached to or removed from the base jack. This segmentation allows the lifting force to be increased by adding only the necessary boost components rather than redesigning the entire jack system.
Solution Approach 2:
The modular boost system is designed to be universally applicable to different jack configurations and well tool types. The adjustable plate can be positioned at various heights, and the coupling mechanisms can accommodate different connection points, making the same boost system suitable for multiple lifting scenarios and reducing the need for multiple specialized jack sizes.
2Adaptability or versatility
If multiple jack sizes are used to provide different lift capabilities, then adaptability is improved, but device complexity increases
Solution Approach 1:
Instead of maintaining multiple jack sizes (small, medium, large), the invention uses a single standardized base jack combined with a modular boost system that can be added as needed. The boost system itself is designed with universal coupling mechanisms and an adjustable plate that can accommodate various lifting requirements, providing the adaptability of multiple jack sizes while simplifying inventory and reducing overall system complexity.
Solution Approach 2:
The adjustable plate within the boost system can be dynamically repositioned to different heights and configurations depending on the specific lifting task. This dynamic adjustability allows the same physical boost system to adapt to different well tool sizes and lifting scenarios, replacing the need for multiple fixed-size jacks.
3Adaptability or versatility
If a modular boost system is added to increase lifting capacity, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The system is segmented into a standardized base jack and a separate modular boost system. The base jack can be manufactured once in large quantities as a standardized unit, while the boost system is a separate module that can be manufactured independently and attached only when additional lifting capacity is required. This reduces the manufacturing cost compared to producing multiple complete jack variants.
Solution Approach 2:
The modular boost system is designed as a universal component that can be attached to various base jack configurations and used with different well tools. By creating a single universal boost module rather than multiple specialized jack types, the manufacturing cost is reduced through economies of scale while maintaining adaptability across different applications.

Function Achieved in This Case
The modular boost system significantly increases the jack's lifting capacity, allowing for the effective dislodging of stuck well tools while being physically smaller, cheaper, and more flexible than traditional solutions, reducing the need for multiple jack sizes and promoting standardization.
Implementation Method 1
a boost cylinder that is removably couplable between the adjustable plate and the base for selectively supplying an additional lift capability to the jack
Implementation Method 2
at least one hydraulic cylinder that is coupled between a base plate and the movable plate for applying force to the movable plate to move the tubing string through the wellbore

AI summary
A modular boost system can be added to a jack to enable greater lift capacity of the jack. One example can involve a jack that is positionable at a well surface for moving a tubing string through a wellbore in a subterranean formation. The jack can include a frame and an adjustable plate that is alternately (i) attachable at a stationary location in the frame for fixing the adjustable plate at the stationary location or (ii) detachable from the stationary location in the frame to enable the adjustable plate to vertically move within the frame. A boost cylinder can be removably coupled to the adjustable plate and a base for selectively supplying an additional lift capability to the jack.
