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.
