Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of downhole tools in wells is complex, unsafe, and costly due to high mechanical tension, requiring multiple deployment devices and a slow process that increases safety risks and operational costs.
Innovation Solution
A single deployment device with a latching compartment and clamp system that secures the downhole tool's fishing neck, allowing for efficient and safe deployment by reducing the need for multiple devices and minimizing operator risk through controlled tension management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple deployment devices are used to manage the weight and tension of downhole tools, then the safety and control of deployment is improved, but the device complexity and operational time increase
Solution Approach 1:
The deployment device is divided into two functional parts: a fixed support structure and a movable clamping mechanism. The clamping mechanism can be independently positioned and locked onto the fishing neck, while the support structure remains stationary. This segmentation allows the complex clamping function to be isolated from the simple support function, enabling safer deployment with reduced overall device complexity.
Solution Approach 2:
The fishing neck acts as an intermediary element between the downhole tool and the deployment device. The clamping mechanism engages with the fishing neck to provide controlled tension management, while the fishing neck transmits forces to the downhole tool. This intermediary approach allows for safer, more controlled deployment without requiring multiple complex deployment devices.
2Reliability
If multiple deployment devices are used to support and lower downhole tools, then the control and safety of operation is improved, but the deployment time and productivity decrease
Solution Approach 1:
The invention merges the support function and the clamping function into a single integrated deployment device. The fixed support structure and movable clamping mechanism work together as one unit, eliminating the need for multiple separate devices. This merging maintains operational control while significantly improving deployment speed and productivity.
Solution Approach 2:
The clamping mechanism is pre-positioned and pre-configured to engage with the fishing neck before the actual deployment begins. The support structure is预先 set up to bear the weight of the downhole tools. This preliminary preparation allows for rapid, controlled deployment without requiring multiple devices to be assembled and positioned during the operation.
3Reliability
If the deployment process is made slower and more controlled, then safety and operator protection is improved, but the operational cost and time increase
Solution Approach 1:
The deployment device is designed to be self-regulating through its mechanical structure. The clamping mechanism automatically locks onto the fishing neck at the correct position, and the support structure self-adjusts to bear the appropriate load. This self-service design ensures safe, controlled deployment without requiring multiple devices or extended operational time for manual adjustment.
4Device complexity
If a single deployment device is used to lower downhole tools, then the device complexity and cost are reduced, but the ability to manage high mechanical tension and weight increases difficulty
Solution Approach 1:
The clamping mechanism is designed with dynamic positioning capability, allowing it to adjust and lock at various positions along the fishing neck. This dynamic feature enables the single deployment device to manage varying mechanical tensions and weights effectively, maintaining simplicity while handling the forces required for safe deployment.
