Movable Plate Well Intervention Apparatus for Rapid Device Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing well intervention technologies face inefficiencies and high costs due to the time-consuming process of switching between different well intervention devices, such as coiled tubing and wireline lubricators, which require disassembly and reconfiguration of complex rigging systems.
Innovation Solution
A well intervention apparatus with a movable plate and track system allows for the sliding attachment of a reception plate and tower, enabling the efficient alternation between coiled tubing and wireline equipment without moving the base frame assembly, facilitating quick switching between different intervention devices by sliding the moveable plate along a track and using hydraulic cylinders for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireline lubricator is suspended from the tower, then wireline operations can be performed, but coiled tubing operations cannot be performed simultaneously and device switching requires time-consuming disassembly and reconfiguration
Solution Approach 1:
The well intervention apparatus is divided into separate functional modules: a fixed tower structure and a movable plate assembly that can be independently positioned. The movable plate carrying the coiled tubing injector head can be slid along the tower track to different positions, allowing different devices to be deployed without disassembling the entire rig structure.
Solution Approach 2:
The system transitions from a static, fixed configuration to a dynamic, reconfigurable system. The movable plate assembly can slide along the tower track and be positioned at different locations, enabling the same physical structure to support different well intervention devices at different times without requiring complete disassembly and reassembly.
2Ease of operation
If wireline lubricator is suspended from the tower, then wireline operations can be conducted, but the complex rigging system requires extensive disassembly for device switching
Solution Approach 1:
The rigging system is segmented into modular components where the movable plate assembly carrying intervention devices can be independently manipulated along the tower track. This segmentation eliminates the need for complex disassembly of the entire rigging system when switching between wireline and coiled tubing operations.
Solution Approach 2:
The tower structure with its track system serves multiple functions: it can support both wireline lubricators and coiled tubing injector heads, provide positioning mechanisms for different devices, and enable rapid deployment of various well intervention equipment without requiring device-specific rigging configurations.

AI summary
A well intervention apparatus including a base frame assembly, a deck attached to an upper end of the base frame assembly. The deck includes a passage and a hatch adjacent to the passage. A track is disposed within the passage, and a movable plate is slidingly attached to the track for movement within the passage. A reception plate is attached over a first aperture of the moveable plate and a tower is mounted over a second aperture of the moveable plate. A primary hoist assembly is connected to an upper end of the tower. The reception plate is configured to secure a first well intervention tool, and the primary hoist assembly is configured to suspend a second well intervention tool from the tower. In a first position of the moveable plate, the reception plate is disposed over the well. In a second position, the tower is disposed over the well.
