Compound Drive Drilling Rig
|
 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.
-
Drawworks is inner speed change.
Speed shift adjustment and change is easily available by remote
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 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 .All operations by driller can be completed
in the cabin for better working conditions and less working
strength.
-
Top drive drilling system can be
equipped.
-
Integrated skid rail may be
provided to meet requirements for cluster well drilling.
