Yongming DQZ Series Top Drive

Advanced Yongming DQZ Series Top Drive System for Efficient and Safe Drilling Operations

The Yongming DQZ Series Top Drive is a modern drilling solution installed at the top of the derrick, replacing conventional rotary table systems as the primary source of drillstring rotation. By enabling continuous rotation while running in or pulling out of the hole, the system significantly improves drilling efficiency, reduces connection time, and enhances operational safety.

Combining advanced mechanical, electrical, and hydraulic technologies, the Top Drive System provides precise control of torque, rotational speed, and drilling direction. It is particularly effective in directional, horizontal, extended-reach, and deep-well drilling applications where uninterrupted rotation and accurate drilling control are essential.

Designed to meet demanding oil and gas drilling requirements, the system incorporates integrated well-control features, automated pipe handling capabilities, and API-compliant safety systems to maximize productivity while minimizing operational risks.
