Major features:
It adop ts 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 requirements .
Major modules of the rig equip trailer device to meet the requirement of fast transportation.
Driving of RT, DW and mud pump is independent, RT rev, torque and mud pump stroke can be adjusted separately as per drilling technology, which provides precondition and guarantee for drilling technology optimization and auto-bit-feeding realization.
RT and auto-bit-feeding both adopt all-digital auto control technique, so drilling operation can be done through optimized drilling parameters, which will reduce labor intensity significantly and improve work efficiency. Display, restoration, regulation and control, remote management of major drilling parameters can be realized.
