A new controlled directional oil well of more than 2660 meters depth was built in Em-Egovskoe oil field in Khanty-Mansiysk Autonomus region

A new controlled directional oil well of more than 2660 meters depth was built in Em-Egovskoe oil field in Khanty-Mansiysk Autonomus region for ROSNEFT company. A drilling rig ZJ-50DBS equipped  with a top drive DQ50B-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.

DQ50B-JH as well as DQ50BQ-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 500hp 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 40 kNm.
