COMPOUND DRIVE DRILLING RIG 3000m-7000m

ZJ30LDB、ZJ40LJDB、ZJ50LJDB、ZJ70LDB

Compound drive driling rig drive rotary table is driven by electric motor, drive drawwork and mud pump aredriven by diesel engine, lt cuts high cost of electric , shortens drive drill rig mechanical transmission distance, alsosolves the problem of high drill floor rotary table drive transmission of mechanical drive rig. The compound drive righas met the requirements of modern drilling technology, it is truly competitive in the market.Main models:ZJ30LDB,ZJ40LJDB,ZJ50LJDB.ZJ70LDB etc.

The drawworks and mud pumps are driven by "diesel engine+torqueconverter or coupling transmission+chain compound" while rotarytable is driven by AC VFD motor or DC motor to obtain smooth speedchange and torque limit for better drilling performance;

Rig floor is in two levels.Power and transmission system are installedon the rear low level;Drawworks is inner speed change.Speed shift adjustment andchange is easily available byremote pneumatic control;Main brake is hydraulic disk and auxiliary brake is electric magnetic

eddy brake;Box or front level with swing lift and rear level with box typesubstructure is available;

Ample space on rig floor is available for convenient operation;Module design is provided for reasonable arrange-ment, power

compensation and high use ratio;

Compound can be used to drive the energy saving generator and

automatic air compressor:

Top drive drilling system can be equipped;

Integrated skid rail may be provided to meet requirements for clusterwell drilling.
