A Using a top drive DQ70BS-JH a new oil well of more than 3670m depth was drilled in Khanty-Mansyisk Autonomous Region

A new controlled directional production oil well of more than 3670 meters depth was built on Tagrinskoye oil field in Khanty-Mansyisk Autonomous region for Russneft company. A drilling rig 3000 EUK-1M equipped with SLC-JH top drive DQ70BS-JH was used for this purpose. A top drive field service support was provided by SLC service engineers working 24 hours 7 days a week.

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.
