Major features:
It adopts integrated design of mechanical, electrical
and digital , its major functions realize digital control, and it
possesses elementary functions of automation, intelligence and
information . Structure design of rig components adopts advanced and
proven technology from China and Overseas, which has advantages of
reliable operation, convenient transportation and economic running to
meet HSE requiremets .
Electric transmission adopts vector VF driving
system, major electric equipments are placed in VFD house and top drive
VFD system can be integrated in. Furthermore for mud pump set electric
control system, it can meet the control requirement after upgrading to
three sets of 2200HP mud pump.
This rig is equipped with an integral driller's
cabin, in which a driller can finish major operations, and it achieves
real time display, memory, print and management of parameters (signal).
In addition, top drive operation can be realized through the touch
screen on driller's seat.
