Sliding Block Spear - Internal Fishing Spear for Drill Pipe, Tubing & Downhole Junk Retrieval
Product Overview

The Sliding Block Spear is a versatile internal-fishing downhole tool widely deployed in oil-well workover operations. It engages internally with fish items that feature a bore inner-passage to retrieve lost down-hole components including drill pipe, tubing, washover pipe, liner, packer, and water distributor.

Besides standard fishing retrieval, this spear supports back-off operations for stuck fish. It can be run in combination with other service tools such as drilling jars and back-off tools to complete complex downhole jobs in one trip.

The tool features compact and simple mechanical structure, easy field operation, and convenient on-site maintenance. It is a reliable common-use fishing solution for various well-repair fishing scenarios.
