Using the top drive DQ70BSQ-JH a new production gas well of more than 4470 meters depth was drilled in Krasnoyarsk region

A new controlled directional oil well of more than 4470 meters depth was built on Kuymbinskoye gas&oil field in Krasnoyarsk region. A drilling rig BK-225E equipped with a powerful top drive DQ70BSQ-JH was used by BNGRE professionals to build this oil well. 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 SSK company.

The DQ70BSQ-JH is one of the high performance models of top drives which provides drilling of the wells up to 7000 meters deep (with a 114 mm drill pipe). The top drive is equipped with two asynchronous frequency controlled electric motors with a power of 600 hp each. This allows to perform drilling with a smooth shaft speed changes in the range from 0 to 220 rpm and with a working torque of up to 65 kNm.
