Using a top drive DQ40BQ-JH a new oil well of more than 3120m depth was drilled in Orenburg region

A new production oil well of more than 3120 meters depth was built in Orenburg region. A drilling ZJ-40 equipped with a top drive DQ40BQ-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 according to service agreement with a drilling company.

The DQ40BQ-JH is an optimal choice for using with fixed and heavy-class mobile drilling rigs. It allows to build fishbone oil wells of up to 4000 meters depth (using drilling 144mm tubes) as quickly as possible. The top drive is equipped with an asynchronous frequency controlled electric motor of 500hp power. This allows to drill with a smooth shaft speed changes in the range from 0 to 180 rpm and with a working torque of up to 40 kNm.
