Using a top drive DQ50BQ-JH a new production oil well of more than 2040 meters depth was drilled in Khanty- Mansiysk Autonomous region

03.06.2023

During 11 days a new controlled-directional oil well of more than 2040 meters depth was built on Kamennoye oilfield in Khanty-Mansiysk Autonomous region. A drilling rig Uralmash USPK-250 equipped with a top drive DQ50BQ-JH was used by RN-Burenie professionals to build this oil well. To achieve an optimal drilling speed an oil-base mud was used. A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week with a drilling crew under service agreement with RN-Burenie company.

The DQ50BQIII-JH as well as DQ50BQ-JH and the DQ50B-JH is the most popular top drive 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.
