ZJ30/1700DB rig is driven by AC variable frequency motor. According to the function, it is divided into the following major areas: drilling platform, power and electric supply area, pump area, solid control area, oil tank area and other devices. It is suitable for side drilling well, directional well and vertical well drilling operation within 3000m.
Drawworks and rotary table adopt independent driving mode. The drawworks is driven by one 600kW AC variable frequency motor; the rotary table is driven by one 300kW AC variable frequency motor. Two sets of F-500 mud pumps are respectively driven by two YJ23A 500kW AC variable frequency motors.
Features
1. The rig adopts modular design, and installation and transportation time is less, which can realize quick movement and disassembly.
2. Mast is front open-face "K" type mast with two-section telescoping structure. It raises and lowers by its own power; substructure is high-low position hydraulic telescoping structure, installed at low position and raised integrally.
3. The rig is driven and controlled by AC frequency conversion mode, with special driller console. All air hoses and oil tubes adopt quick acting couplings and are marked clearly.
