DRILLER OPERATION CONTROL SYSTEM

It transfers data through PLC、PROFIBUS-DP bus to control drawworks, rotary table, mud pump and automatic driller, and monitor them by industrial control computer. The integrated driller operation control system adopts the positive pressure explosion-proof technique and conforms to API RP500 criteria. It has the following control functions: making a trip and traveling block position, automatic/manual driller, disc brake and dynamic brake, rotary table speed and torque, mud pump stroke, as well as mechanical, electrical, hydraulic and pneumatic PLC programmable.

INTEGRATED INSTRUMENT CONTROL SYSTEM

Transfer various of drilling data into PLC through the sensors, encoders, transducers and other collecting units, after calculation and processing, the following drilling parameters could be displayed on the touch screens, the industrial control computers and the remote terminals: hook load, WOB, well depth, drilling speed, rotary table speed, rotary table torque, pump stroke, pump pressure, liquid level of mud pool, mud return volume, total pumping times, traveling block position, ton/km and other parameters.

TRAVELING BLOCK SAVER CONTROL SYSTEM

Automatically control the running position of traveling block and prevent it from any accidents through the drum encoder and control system.

MAGNETIC EDDY CURRENT BRAKE CONTROL SYSTEM

It is used for controlling the brake moment of the magnetic eddy current brake device to lower the traveling block steadily through the brake control system.
