9000m Digital control VF electric rig
ZJ90/6750 DBS
Drilling module |
Main features of drilling rig:
The rig is designed integrating mechanical , electrical and digital technologies with advanced and proven technology from China and o verseas , while main functions realizing digital control; possesses elementary functions for automation, intelligence and information gathering , its design meets HSE requirements. Hence, its operation is reliable with easy transportation and economic running.
Electric transmission uses a vector VF drive system, main electric equipments are in VFD house where top drive VFD system is integrated. In addition, mud pump set electric control system meets the requirements to upgrade to 3 sets of 2200HP mud pump set control.
Integrated driller's cabin makes the driller fulfill the main operation of drilling rig in the cabin, realizing display, memory, print and management of parameters (signal) at real time. In addition, top drive operation can be realized by touch screen on driller's chair.
