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