The function of the top drive single guide rail is to provide vertical sliding guidance for the top drive, playing a supporting role to facilitate the connection of the kelly and the centering of the casing during casing running. It also offsets the reaction torque from the rotating drill string during drilling, transmitting the reaction torque to the derrick base instead of the derrick itself. All parts of the top drive guide rail produced by our factory are made of high-quality structural steel and alloy structural steel. The connecting lugs are heat-treated, with high tensile strength and good weldability. Its function is to drive the drill string rotation and provide reaction torque strength. It provides a track for the top drive unit to move up and down during normal drilling and rig-up/rig-down operations.

QYZ type full hydraulic directional drilling impactor
In normal drilling operations, downhole drill string combinations are often stuck due to various reasons. A shock absorber is an effective tool for un-sticking. The QYZ type fully hydraulic shock absorber is an up-and-down integrated shock absorber. When the downhole drill string is stuck, the shock absorber can be activated by lifting or lowering the drill string to generate upward or downward shock force, allowing the drilling operation to proceed smoothly. This type of shock absorber has the advantages of simple operation, stable performance, safety and reliability, and convenient maintenance.

YJZ type hydraulic mechanical follow-up drill impactor
The YJZ hydraulic mechanical downhole impactor is a new type of downhole impactor that combines hydraulic and mechanical principles. This product is suitable for various drilling operations and is run with the drill string. During normal drilling operations, downhole tools often get stuck for various reasons, and the impactor is an effective tool for freeing stuck tools. When downhole tools are stuck, raising and lowering the drill string causes the impactor to generate upward or downward impact force. Through repeated impacts, obstructions and stuck pipe can be cleared, quickly restoring normal drilling operations. This also avoids obstructions or stuck pipe escalating into accidents, causing greater economic losses. If the release force is not qualified, it can be dynamically adjusted on site at any time.

SJYZ type double-acting mechanical hydraulic downhole impactor
The SJYZ type double-acting mechanical hydraulic downhole hammer is an integrated up-and-down striking mechanical hydraulic downhole hammer. This product combines the advantages of both mechanical and hydraulic downhole hammers, suitable for various drilling operations and used with downhole drilling tools. When the downhole drilling tools are stuck, lifting and lowering the drill string causes the hammer to generate upward or downward impact force. Through repeated impacts, obstructions and stuck drills can be removed, quickly restoring normal drilling operations. This also avoids obstructions or stuck drills escalating into accidents, causing greater economic losses. If the release force is not appropriate, it can be dynamically adjusted on site at any time.

The square drill stem valve, also known as a square drill stem cock or drill stem safety valve, is a manually controlled valve in the drill string circulation system and is one of the effective tools for preventing well blowouts. Square drill stem valves are divided into upper and lower square drill stem valves. The upper square drill stem valve is used between the lower end of the faucet connector and the square drill stem. The lower square drill stem valve is used between the lower end of the square drill stem and the upper end of the drill stem. It can be switched on or off by rotating it 90° with a special wrench according to the instructions. In drilling operations, square drill stem valves should be installed at both the upper and lower ends of the square drill stem to prevent the loss of drilling fluid and well blowouts, thus avoiding serious accidents.

The tubing swivel valve, also known as a tubing cock, allows drilling fluid to flow freely without pressure drop. This type of valve is installed above the tubing to control wellhead pressure and prevent fluid loss when the tubing is removed.
