Packing & Delivery

As the key locking mechanism of VARCO top drive, the shoot pin assembly is made of high-strength alloy steel and integrated inside the top drive drilling device. The core transmission part includes precision-machined shaft pins, hydraulic drive modules and guide rails to ensure accurate positioning and fast response of the shooting pin action. The shaft pin is treated with a wear-resistant coating to cope with high friction and corrosive media in drilling operations.To adapt to high pressure (up to 70MPa or more) and high temperature (120ºC or more) environments, the ejector pin assembly is equipped with a multi-pass sealing structure. The main seal uses a metal-rubber composite seal ring, supplemented by a redundant seal design to prevent drilling fluid from penetrating into the internal transmission components. The lubrication system uses oil circulation or grease lubrication to reduce the wear of the shaft pin and the slide rail and extend the service life.

FAQ

The core function of the shoot pin assembly :

1. Quick connection and locking of drill string

During the process of connecting the top drive to the stand or drilling, the shoot pin assembly inserts the shaft pin into the preset hole of the drill string joint through hydraulic drive to achieve a rigid connection between the drill string and the top drive main shaft, ensuring the effective transmission of torque (up to 40kN·m) and axial force (≥500T). Compared with traditional rotary drilling, the shooter pin locking can reduce the make-up and break-out operation time by 90%.

2. Back-marking and anti-drilling function

When the drill string is stuck, the shoot pin assembly can remove the jam by continuously rotating and pulling the drill string (back-marking action) while maintaining the circulating drilling fluid. Its fast response characteristics (lock/unlock switching ≤2 seconds) significantly reduce the time for handling stuck drill accidents.

3. Dynamic sealing under high pressure environment

The multi-pass sealing design maintains sealing performance during the reciprocating motion of the shooter pin to prevent high-pressure drilling fluid from entering the transmission components. For example, the primary seal can withstand an instantaneous pressure shock of ≥50MPa, and the secondary seal serves as redundant protection.

4. Safety guarantee and fault redundancy

The mechanical locking and sensor monitoring of the shoot pin assembly form a double safety guarantee. When the hydraulic system is abnormal (such as a sudden drop in pressure), the spring locking mechanism can maintain the shoot pin locked state to avoid accidents where the drill string falls off.
