YTQC Type Drill String Fishing Magnet is one of the auxiliary tools to ensure the normal drilling operation and bottom hole cleaning in the process of downhole accident treatment. The main feature of this product is that it works together with the grinding shoes in the fishing operation, which is different from the previous method of lifting the drill after milling, and then connecting the drill string with the strong magnetic fishing tool to go down the well for cleaning bottom hole , saving a trip down the well operation, which not only saves the drilling cost, but also saves the fishing operation time.
CZJQZ-II 360° Rotation Hydraulic Make/Break unit is designed to safely and efficiently make-up/break-out downholetoolsandmotors. It adopts a unique 360° rotational headstock clamp design. This unit is designed for fast, accurate anddependablemake up and break out of threaded connections. The 360° rotational clamp design greatly enhances the speed andaccuracyofmake-up and break-out of tools.
TIANHE Reverse Circulation Junk Basket (RCJB) is designed to remove all types of small junk objects from the well hole. The tool’s main feature is that it eliminates the possibility of pulling a wet string during fishing operation with its reverse drainage design.

Application
It is suitable for all conventional wells, inclined wells and large displacement wells at all temperatures not higher than 160℃ .
Features
The superior machine structure is to further improve the machine maintainability.
The better sealing materials are selected to improve the reliability of sealing
The core mechanism adopts the seal oil bath design to reduce the wear and tear of the moving parts and improve the life of the whole machine.
The overflow area of the release channel is increased to reduce the running resistance and greatly improve the shock effect.
The operating force of hydraulic releasing mechanism can be controlled on the ground by driller, and can be flexibly adjusted according to the downhole situation.
The optional mechanical locking module is added to meet the needs of some special users. Increase the fast recovery function of the upward and downward strokes.
The mandrel moves back to the middle position, and then the jar will do jarring again in either of the two directions.
