SECTION 13 INSTRUMENTATIONS A. 1 ea Driller’s control cabin Features： Room to accommodate brake control, drilling instrumentation, air control, VFD control, and others control are all located in this cabin. This driller’s control cabin is t he control center of rig where driller operates and monitors drilling condition. The rig operation is conducted by driller from driller’s chair, having clear view of drill floor, monkey board and traveling block. Complete with microphone, four cameras for monitoring drawworks, mud tank area, mud pump and racking board. As observation window, the house roof adopts safety glass and equipped with protected fence. Complete with explosion proof air conditioner. B. 1 set Weight indication system Model JZ500A Lone line/ maximum load 12/4920KN 10/4100KN Output pressure of deadline anchor 6.83MPA Error of output pressure of deadline anchor 1.0% Basic error of weight indicator 1.0% Basic error of weight indicator system 2.0% Sensitivity 25.0KN No leakage should occur to the hydraulic system of the weight indicator system even under the maximum working pressure. -40℃～50℃
Working temperature: Pressure transmission medium
45# transformer oil
C. 1 ea Drill watch system The drilling monitor displays all parameters in touch screen to convenient for observe data by driller’s man and decide the drilling operations. The whole system consist of 9 set measurement system, i.e. weight of hook measurement system (include weight of hook), stand pipe pressure measurement system (pump pressure), rotary table torque measurement system, rotary table speed measurement system, tong torque measurement system, parameters related to mud (include SPM, mud flow, mud volume, etc.), and well depth measure system (including bit position, etc.). Besides, also complete with display console, industrial computer, sensors, DAQ, pressure transducer, power supply, UPS, hoses, cables and installing assemblies. The system consists of sensors, DAQ system and host processing system. Sensors transmit the original signals to electrical signals, and the electrical signals are processed in DAQ then they are read on meters and input to host processing system. Computer will store and process the data. In addition, alarm is available when there is an abnormal data. Touch screen which is installed in driller’s cabin will display all the parameters for easy watching. What’s more, weight of hook, rotary table torque, and stand pipe will be show through traditional gauges. Also, these traditional gauges are mounted in driller’s cabin. DAQ is an important component in the whole system. It acquires and processes the signals, - 37 -
then input to computer to display or alarm driller’s man whenever necessary. The whole system is communicated through 485 fieldbus. It will help system to realize intelligent control as well as process, storage, printing, and remote transmission of data. The company man offices are furnished with the system to monitor the data real-time. Weight of hook: the signal comes from the pressure sensor which is installed on deadline anchor. The scope of measurement is 0-4920KN. Rotary table speed (RPM): the signal comes from the proximity sensor near to the input shaft which is between rotary table drive motor and gear box. The scope of measurement is 0-300RPM. SPM: the signal comes from a proximity sensor which is installed near to driving shaft. The scope of measurement is 0-200SPM. Rotary table torque: the signal comes from the current transformer. The scope of measurement is 0-62KN.M. Stand pipe pressure (pump pressure): the signal comes from a 2”sensor assembly standpipe manifold. The scope of measurement is among 0-40Mpa. Tong torque: the signal comes from tension load cell assembly. The scope of measurement is 0-100KN. Well depth: the signal comes from rotary encoder which is equipped on the left side of drum. The scope of measurement is 0-9999m. Mud flow: the signal comes from mud outlet flow sensor which is installed on mud outlet return flow pipe. The scope of measurement is 0-100%. Mud volume: the signal comes from ultrasonic sensor which is installed on the surface of each mud tank. The scope of measurement is 0-80m3. D. 1 ea TV monitor Function Monitoring area: monitor the pump area, tank area, drum and racking platform simultaneously. Four cameras (four with tilt heads) are controlled by control panel; their images are displayed on the 21” LCD monitor which is located on the drilling operation panel, in the form of single channel or four channels synchronously. All the cameras and platforms can be controlled by control panel, and such functions as pan/tilt and zoom/focus can also be adjusted through control panel. with also Four cameras all-weather explosion Proof guard & pedestal for monitoring draw works, mud control systems, mud pumps, shale Shaker area and racking board on LCD color 21” monitor with four frame function, multifunctional controller as integrated with capability as four display and location, switch over, zooming, panning & etc.
