It solves the high-climbing drive turntable problem of rotary table of mechanical drilling rig.
Compound drive drilling rig are.
simple structure, layout flexibility, energy-saving and efficient.
The drawworks and mud pumps are driven by "diesel engine+torque converter or coupling transmission+chain compound" while rotary table is driven by AC VFD motor or DC motor to obtain smooth speed change and torque limit for better drilling performance.
Rig floor is in two levels. Power and transmission system are installed on the rear low level.
Main brake is hydraulic disk and auxiliary brake is electric magnetic eddy brake or pneumatic drive and water-cooled disc brake. Drawworks is inner speed change. Speed shift adjustment and change is easily available by remote pneumatic control.
Box or front level with swing lift and rear level with box type substructure is available.
Ample space on rig floor is available for convenient operation. Module design is provided for reasonable arrangement, power compensation and high use ratio.
Compound can be used to drive the energy saving generator and automatic air compressor.
A separate driller cabin is fitted operations for air, electric and hydraulic, drilling data and parameters are all in the cabin. Logic control, supervision and maintenance during complete drilling operations are available by PLC processes. The drilling data can be stored, printed and remote transmitted.
The auto driller system and top drive drilling system can be equipped.
Integrated skid rail may be provided to meet requirements for cluster well drilling. |
