15.10.2021

A new production horizontal oil well of more than 4400 meters depth was built on Vyngayakhskoe oil field in Yamal-Nenetsk Autonomous region for GazpromNEFT company by NaftaGaz-Burenie. A drilling rig Uralmash 3900/225 EK equipped  with a top drive DQ50B-JH was used for this purpose. 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 NaftaGaz-Burenie.

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