Using the top drive DQ70BS-JH a new production gas well of more than 5830 meters depth was drilled in Yamal-Nenetsk Autonomous region

A new horizontal gas well of more than 5830 meters depth was built on Urengoiskoye gas&oil field in Yamal-Nenetsk Autonomous region. A drilling rig ZJ-50DBS equipped with a powerful top drive DQ70BS-JH was used by SSK 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 DQ70BS-JH is one of the SLC-JH 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 422 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 55 kNm.
