Using a top drive DQ70BSQ-JH a new production oil well of more than 4260 meters depth was drilled in Krasnoyarskiy kray

A new horizontal production oil well of more than 4260 meters depth was built in Shinginskoe in Krasnoyarskiy kray. A drilling rig Uralmash 5000/320 EK-BMCH equipped with the top drive DQ70BSQ-JH was used to build 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 4260 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.
