Hydraulic Inflow Valve Actuation for High-Pressure Well Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inflow control devices (ICDs) in wellbores face limitations due to limited magnetic coupling forces and size constraints, which hinder effective control of fluid production, particularly in high-pressure environments, leading to challenges in selectively producing desired fluid components like oil while minimizing gas or water production.
Innovation Solution
Implementing a hydraulic system with solenoid valves to control actuators in ICDs, utilizing a high-pressure fluid reservoir for enhanced force and debris tolerance, replacing magnetic coupling with hydraulic linkages for improved actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If magnetic coupling is used to actuate the production valve, then the device can be controlled remotely, but the magnetic coupling force is limited and insufficient for high-pressure environments
Solution Approach 1:
The patent replaces magnetic coupling with a hydraulic actuation system where hydraulic fluid is delivered to a chamber to move the production valve. This hydraulic system provides significantly higher actuation force compared to magnetic coupling, enabling reliable valve control in high-pressure wellbore environments while maintaining remote control capability through solenoid valves.
2Force
If the ICD size is constrained, then the device can be installed in existing wellbores, but the magnetic array coupling force is reduced
Solution Approach 1:
The patent eliminates the magnetic array by using a hydraulic actuation system. The hydraulic fluid is delivered through a hydraulic passage to a chamber that directly actuates the production valve. This approach provides sufficient coupling force without requiring a large magnetic array, thereby maintaining compatibility with existing wellbore size constraints.
3Ease of operation
If magnetic coupling is used, then the actuator can be contained in an atmospheric chamber, but the system has limited debris tolerance
Solution Approach 1:
The patent replaces the magnetic coupling system with a hydraulic system where hydraulic fluid is delivered to a chamber to actuate the production valve. This hydraulic approach provides superior debris tolerance compared to magnetic coupling, as the hydraulic fluid can be filtered and the system can operate reliably in the presence of wellbore debris, while still allowing the actuator to be contained in a sealed chamber.
