Using a top drive DQ50BQ-JH a new production oil well of more than 3300 meters depth was drilled in Khanty-Mansiysk Autonomous region

A new horizontal production oil well of more than 3300 meters depth was built in Khanty-Mansyisk Autonomous region. A drilling rig USPK-250 equipped with a top drive DQ50BQ-JH was used by RN-Burenie professionals to build this well. A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week according to service agreement with RN-Burenie company.

The DQ50BQ-JH as well as the DQ50B-JH and the DQ50BQIII-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.
