A top drive DQ-50B-JH was used for drilling a new controlled directional oil-well of more than 3520m depth on Priobskoe oil-field in Khanty-Mansiysk Autonomous Okrug

A new controlled directional oil-well of more than 3520m depth was built on Priobskoe oilfield in Khanty-Mansiysk Autonomous Okrug for ROSNEFT company. A drilling rig "BU-4000 EKBM" equipped  with a top drive DQ50B-JH  was used for this purpose.

The top drive system DQ50B-JH allows to drill with:

• rotation speed  - up to 180 rpm/min;
• torque  - up to 40 kNm.

Our customers were satisfied with the reliability, security and performance of equipment, the quality and the timing of our work. 

Our top drives are effective in the drilling of obliquely-directional and horizontal wells with long borehole.
