Manipulation Tool for Well Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing well manipulation tools face challenges in efficiently operating well devices, particularly due to frictional losses and difficulty in transmitting forces at deviated well paths, leading to inefficient operation and uncertainty in force application, especially when operating valves and plugs in wells with significant vertical deviations.
Innovation Solution
A manipulation tool with an elongated housing featuring a gripping device for releasable engagement, axial and rotational manipulation devices, and driving mechanisms to control energy supply, allowing precise torque transmission and independent control of rotational and axial movements, reducing frictional losses and enabling repeated use without extraction from the well.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If forces are transmitted from the well surface to operate well devices, then the well devices can be operated, but frictional losses occur and force transmission becomes uncertain in deviated well paths
Solution Approach 1:
The patent replaces the conventional mechanical force transmission system (drill string, cable) with an electromagnetic system. A manipulation tool with electric motors is lowered into the well and operated remotely, eliminating the need to transmit mechanical forces over long distances through deviated well paths. This substitution resolves the frictional losses and force transmission uncertainty while maintaining well device operability.
2Productivity
If conventional manipulation tools are used, then well devices can be operated, but operation time and resource expenditure increase
Solution Approach 1:
The manipulation tool is designed to be self-contained with integrated electric motors, manipulation devices, and control systems. It can perform multiple operations (rotational, axial, lateral movements) without requiring retrieval and replacement, enabling repetitive use and reducing operation time. The tool serves itself by containing all necessary components within the housing, eliminating the need for external support equipment during operations.
3Measurement precision
If forces are applied through drill string or cable, then well devices can be actuated, but control precision and force application accuracy decrease
Solution Approach 1:
The manipulation tool segments the force application function into independent electric motors located within the housing. Each motor can be controlled separately to provide precise rotational and axial movements. This segmentation allows for accurate control of manipulation devices without the complexity of long-distance mechanical force transmission through drill strings or cables.

AI summary
This invention relates to a manipulation tool and method for connection and operation of a controllable well device and adapter. The tool includes an elongated housing with first and second end portions, a gripping device in the first end portion provides releasable engagement with the well device controllable by means of the manipulation tool. The gripping device includes means for resisting rotational and axial movement between the housing and the well device. At least one manipulation device is axially displaceable between a first and second position along a longitudinal axis of the housing and rotatable around the longitudinal axis of the housing. A first driving device produces axial displacement of the at least one manipulation device, and a second driving device produces rotation of at least one manipulation device. The first and second driving devices are connected to a control unit for controlling energy to the driving devices.
