Detailed introduction
1. Compact design
The structure is compact, 250T and below models can be installed on the truck-mounted drilling rig, and the installation is quick.
2. Easy to disassemble and assemble guide rail
The guide rail adopts patented hook structure, which is convenient and quick to disassemble and save time.
3. Spindle rotation positioning control function
It can accurately locate the rotation angle of the drilling tool, making the guidance of the directional well horizontal well easier and more accurate.
4. System redundancy design
The system adopts double PLC structure, data wireless transmission, and a backup system, reliable operation.
5, Integrated hydraulic system
The hydraulic system is integrated on the top drive body, which does not require on-site installation and disassembly of pipelines, saves time, reduces the probability of contamination of the hydraulic system, and improves the reliability of the hydraulic system.
6. Formulation design
A variety of drilling conditions and top drive parameter setting optimization schemes are built in to reduce manual training time.
7. Drilling rig integrated control interface technology (provide interface)
The data acquisition and status monitoring between the top drive device and some devices/equipment such as drilling rig transmission components, circulation system and downhole instruments are realized, and the integrated intelligent control of drilling rig is realized.
8, Soft torque control technology
By collecting load, torque and speed and other related parameters, the system is optimized to ensure drilling safety.
9. Rotation head 360 °
The rotary head can rotate 360 °, which increases the flexibility of the top drive, is convenient for field operation and reduces labor intensity.
