A new controlled directional oil well of more than 3170 meters depth was built by RN-Burenie in Prirazlomnoe oil field in Khanty-Mansyisk Autonomous region for Rosneft company. A cluster drilling rig Uralmash 4000/250 EK BM equipped with a top drive DQ50BQ-JH was used for this purpose. A non-stop top drive performance was provided by SLC service engineers working 24 hours a day 7 days a week with a drilling crew under service agreement with RN-Burenie company.
The DQ50BQ-JH as well as the DQ50B-JH is the most popular top drive model among drilling companies. It allows to build fishbone wells of up to 5000 meters depth (using drilling 144mm tubes) as quickly as possible. The top drive is equipped with an asynchronous frequency controlled electric motor of 600hp power. This allows drilling with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 48 kNm.
