Major features:
Driving of RT, DW and mud pump is independent, RT
rev, torque and mud pump stroke can be adjusted separately as per
drilling technology.
RT rev adjusting and DW auto-bit-feeding both adopt
all-digital auto control technique, which makes the performance of the
rig under drilling condition get close to digital-control electric VF
rig; driller operates the touch screen to fulfill drilling operation
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.
Major parts as mast, substructure and drawworks etc
can be placed on shifting guide rail, to perform cluster well drilling
by cylinder shifting.
