Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deploying and retracting brushes or scrapers in wellbores during downhole operations are time-consuming, often taking hours or days, and applying pressure using tools like balls or darts can be particularly time-consuming.
Innovation Solution
A tubular cleaning system with a housing containing a deployable tool and a motor activated by a wireless signal, using an actuator to extend or retract the tool, significantly reducing deployment and retraction time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a shifting tool or pressure application method is used to deploy the scraper, then the scraper can be deployed and retracted, but the operational time required is excessive (hours or days)
Solution Approach 1:
The patent replaces traditional mechanical deployment methods (shifting tools, pressure application via balls or darts) with an electric motor system. The motor receives electrical signals through the tubular string and directly actuates the scraper via an actuator mechanism, enabling rapid deployment and retraction without the time-consuming mechanical processes of the prior art.
Solution Approach 2:
The patent introduces a dynamically controllable motor system that can be selectively activated by electrical signals to deploy or retract the scraper on demand. This dynamic control mechanism allows the scraper to be positioned and repositioned rapidly throughout the tubular string, transforming the static, time-consuming deployment process into a dynamic, responsive system.
2Ease of operation
If pressure is applied to deploy the tool, then the tool can be extended, but the process is time-consuming and reduces operational efficiency
Solution Approach 1:
The patent replaces pressure-based deployment mechanisms with an electric motor system that directly actuates the tool. The motor converts electrical energy to mechanical motion, providing precise and rapid tool deployment without requiring time-consuming pressure application and release cycles.
Solution Approach 2:
The patent employs periodic electrical signals to control the motor, enabling the tool to be deployed and retracted on demand. This periodic actuation method allows for efficient, repeated deployment cycles without the continuous pressure application required by traditional methods, thereby improving operational efficiency.
