Wellbore Cleaning Tool Cup Member Debris Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wellbore cleaning tools are ineffective in removing all debris from the wellbore due to the depth and size of debris, leading to residual debris and additional debris suspension during tool removal.
Innovation Solution
A wellbore cleaning tool with a moveable cup member that changes positions to divert fluid flow, allowing debris to be filtered out using a filter member, and equipped with a pressure relief mechanism to prevent excessive pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wellbore cleaning tools are used to dislodge and circulate cleaning fluids to flush out debris, then debris removal capability is improved, but some debris remains suspended in the wellbore and additional debris becomes suspended during tool removal
Solution Approach 1:
The cleaning tool is divided into functional segments: a cup member for capturing debris, a filter member for separating debris from fluid, and a mandrel for structural support. This segmentation allows the tool to perform multiple functions (dislodging, filtering, and retaining debris) in a single operation, preventing residual debris from remaining in the wellbore
Solution Approach 2:
The filter member acts as an intermediary between the cleaning fluid and the debris. It captures and retains debris particles while allowing cleaning fluid to pass through, ensuring that debris is completely removed from the wellbore and will not become re-suspended during tool removal
2Reliability
If a filter member is added to capture and retain debris, then complete debris removal is improved, but device complexity increases
Solution Approach 1:
The filter member is integrated with the cup member and mandrel to form a single unified tool assembly. The cup member, filter member, and mandrel are combined into one device that can be deployed together, capturing debris and filtering it in a single operational step without requiring multiple separate tools or complex assembly procedures
Solution Approach 2:
The cleaning tool is designed as a multi-functional device that combines debris dislodging, fluid circulation, debris capture, and filtration capabilities in a single tool. This universal design achieves complete debris removal without proportionally increasing complexity, as each component serves multiple purposes within the integrated system
3Productivity
If cup member is made moveable between collapsed and extended positions to divert fluid flow, then debris capture efficiency is improved, but device complexity increases
Solution Approach 1:
The cup member is designed to be moveable between a collapsed position (allowing fluid to flow across its exterior) and an extended position (diverting fluid into the first flow path between the inner mandrel and cup member). This dynamic positioning capability allows the tool to adapt its fluid flow pattern based on operational needs, significantly improving debris capture efficiency while maintaining reasonable structural complexity through a single movable component
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively removes debris from the wellbore by circulating cleaning fluids and diverting fluid flow through a filter member, ensuring thorough cleaning and preventing debris suspension during tool extraction.
Implementation Method 1
diverting the fluid disposed above the cup member into the interior of the cup member and through a filter member of the tool to remove debris from the fluid

AI summary
A method and apparatus for removing debris from a wellbore using a cleaning tool. The tool may comprise an inner mandrel and a cup member coupled to the inner mandrel. The cup member is moveable between a collapsed position where fluid may flow across the exterior of the cup member, and an extended position where fluid is diverted into a flow path disposed between the inner mandrel and the cup member. The fluid is diverted through a filter member that is coupled to the inner mandrel below the cup member.
