A fund of production oil wells in Yamal-Nenetsk Autonomous region has been replenished by a new oil well of more than 4020 meters depth

A fund of production oil wells in Yamal-Nenetsk Autonomous region has been replenished by a new horizontal oil well of more than 4020 meters depth.  A state-of-the art drilling rig Uralmash 6000/400 EK BMCH equipped with a top drive DQ70BSQ-JH was used for drilling this oil well. A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week under service agreement with a drilling company.

DQ70BSQ-JH is one of the high performance models of top drives and 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 500 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.
