A fund of Russneft production oil wells in Khanty-Mansiysk autonomous region has been replenished by a new well

A fund of Russneft production oil wells in Khanty-Mansiysk autonomous region has been replenished by a new well.  A drilling rig Uralmash 3000 EUK-1M equipped with SLC-JH top drive DQ70BS-JH was used for construction this oil well. Total penetration during the well drilling amounted to 4500 meters.  A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week according to a service contract with a drilling company.

The DQ70BS-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 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.
