Purpose
The Double Fishneck Knuckle Joint is designed to enhance flexibility within the wireline tool string, allowing it to adapt to various downhole conditions and operational requirements. When a tool string needs to navigate deviated wells, work in crooked tubing, or handle fishing operations in casing through tubing, a knuckle joint comes into play. Before operations, operators must carefully assess well conditions and the placement of the knuckle joint within the tool string. It’s important to note that knuckle joints are not recommended for use in wells with high H2S content. Custom configurations and quick-connect connections are available upon inquiry.
Applications
- Allowing the tool string to adjust its angle, ensuring smooth operations even in non-vertical boreholes.
- Facilitating entries into ON-OFF connectors within the well.
- Assisting in fishing operations within the casing through tubing.
Key Features & Benefits
- The knuckle joint provides the necessary flexibility in situations where the tubing or casing is deviated.
- Flexibility for ON-OFF connectors makes disconnection and reconnection easy during wireline operations.
