Downhole Drilling Tool Fishing Bumper Sub 4 3/4''~8'', Releasing Tool

Fishing bumper sub is a mechanical jarring tool. It can repeatedly jar for stuck drill stem, make stuck point loose and release, when lifting and jarring can not release stuck, it still can rotate to make releasing fishing tools release fishes. When fishing bumper sub works with mechanical internal cutter, it can make internal cutter get preset constant forward force, to cut steadily. When it works with back off tools, it can compensate a rising stroke for connection after back off.

We also produce H2S resistance Jars, which adopt high quality import sulfur-resistance material.
