CHARACTERISTICS AND FEATURES

Adopting advanced full numerical AC VFD technology, intellectual drilling control is accomplished through PLC, touch screen and integrated design of air, electric, hydraulic parts and drilling instrumentation. Large power and wide frequency motors are used for complete range speed setting of drawworks, rotary table and mud pumps. Single shaft, gear drive and one shift smooth speed change drawworks is simple in structure and reliable in operation. Compound hydraulic disc brake and dynamic braking are used for braking system.
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.
Automatic drilling is obtained by drawworks main motor or an independent motor. Real time supervision and control for tripping in, tripping out and drilling operation are obtained.
Intellectual soft starting device, ET200 or ASL module is used for protection and supervision to MCC system. Intellectual position control for traveling block to prevent top and low collision is provided.
Top drive drilling system can be equipped.
Protective functions to air or hydraulic loss, electric control system or motor trouble, limit for rotary torque and pump pressure is available.
Integrated skid rail may be provided to meet reqirements for cluster well drilling.



MECHANICAL DRILLING RIG

CHARACTERISTICS AND FEATURES

Either inner or outer speed change is available for drawworks. Speed change of drawworks is easy and fast by remote pneumatic operation. Main brake is either band brake or hydraulic disc. Electric magnetic eddy brake or EATON brake is optional for auxiliary brake.
For drilling rigs over 4000 meters in drilling depth, rig floor is in two levels. Power and transmission system are installed on the rear low level and the rig power is transmitted to drive rotary table and catworks located on drill floor through bevel gear reducer and universal shaft.
Module is designed for easy assembly and disassembly.
Various drive modes including “diesel engine + torque converter or coupling transmission+chain compound”, ”diesel engine+transmission+v-belt compound”, ”diesel engine+transmission+cardan shaft”, or”diesel engine+transmission+cardan shaft”, or ”diesel engine+transmission+gear compound”are available for customers. The power is reasonably distributed for higher efficiency.
Sand reel, mechanical friction cathead and rotary drive device are equipted.
Top drive drilling system can be installed.
Independent motor automatic drilling system may be offered.
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.
Integrated skid rail may be provided to meet requirements for cluster well drilling.
