A production oil well with a complex profile was built in Krasnoleninskoe oil field in Khanty-Mansiysk Autonomus region

In Krasnoleninskoe oil field, located in Khanty-Mansiysk Autonomus region, the RN-Burenie company has built a complex oil well with two production strings. For building this well RN-Burenie professionals has drilled more than 4850 meters of oil bearing rocks. A drilling rig Uralmash 3000 EUK  equipped  with the top drive DQ50BQ-JH was used for this purpose. A non-stop top drive performance was provided by SLC service engineers working under service agreement with RN-Burenie company.

DQ50BQ-JH as well as DQ50B-JH is the most popular top drive model among drilling companies.  It allows to build fishbone oil 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 to drill with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 48 kNm.
