Features of DC land rig
1. DW, RT and mud pump realize independent DC stepless speed regulation which provide guarantee for drilling technology optimization.
2. Mast, substructure and drill floor equipments can be installed at lower position, and then be lifted integrally upon DW power.
3. Auto-bit-feeding adopts all-digital auto control technique, 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.
