ZJ30 / 1700DB Rig

ZJ30/1700B rig is driven by AC variable frequency motor, According to the function is divided into following major areas: dilling platform,power and electric supply area, pump area,solid control area, oiltank area and other devices.It is suitable for side drilling weall, directionalwelland vertical welldriling operation within 3000m. Drawworks and rotary table adopt independent driving mode. Drawworks is driven by one 600kW AC variable frequency motor, rotary table is driven by one 300kW AC variable frequency motor. Two sets of F-500 mud pumps are respectively driven by the other two YJ23A500kW AC variable frequency motors. The speed of motor used to driving drawworks ischanged by one set two shits transmission to drive drawworks through chain box, and to realize 2+2R gears., Rotary table adopts directconnection between motor and rotary through transmission shaft.

Feature：

1.The rig adopts modular design,and installation & transportation times is less, which can realize to move and disasembely quickly

2.Mastis front open-face,'K" type mast, Itis two-section telescoping structure. Itraising & lower by ts own power, substructure is high-lowposition hydraulic telescoping structure, installation on low position and raising integrally .

3. The rig is driven and controlled by AC frequency conversion mode, which has special driller console. All air hose and oil tubes adopt quickacting coupling and are remarked clearly.
