Using a top drive DQ50B-JH a new oil well of more than 2950m depth was drilled in Tomsk Region

A new controlled directional production oil well of more than 2950 meters depth was built on Shinginskoye gas&oil field in Tomsk region. A drilling rig 3000 EUK-1M 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 company.

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.
