Wireline Tool String-Wireline Spring Jar

Wireline Tool String-Wireline Spring Jar

Product Description

The spring jar is a specialized tool designed for upward jolting in heavy-duty fishing operations. Operating on the shift-flick principle, this tool ensures trouble-free performance with minimal maintenance requirements. Its components include an upper joint, jar cap, jar rod, jar cylinder, spring cylinder, clamp, connecting cylinder, force-adjusting rod, press sleeve, disc spring rod, and lower joint. When the jar is closed, the clasp secures the lower part of the jar rod. During lifting, the jar rod activates the claw, pulling the disc spring rod to compress the stored energy in the disc spring. As the jar rod travels, the jaw separates from the rod, instantly releasing the disc spring energy to achieve the jarring effect.Wireline Spring Jar

Operational Approach

1. Connect the lower end of the spring jar to the tool requiring upward jolting. Lower the tool string to the predetermined position and stop lowering.

2. Gradually lift the tool string, adjusting the lifting force based on the pre-set jarring force. Maintain the lifting force at a consistent level.

3. Continue lifting the tool string at a steady speed until the wire suddenly loses tension, completing the jolt.

4. If the job isn't completed on the first attempt, lower the tool string to reset the spring jar (gripping the lower part of the jar rod) and repeat the jarring process.
