Drilling Parameters Monitor with concentrated electric gauges
Drilling Parameter instrument combines technologies of electron, computer and communication, and it fits electric/mechanical/workover/offshore rigs. It monitors parameters of hook load, rotary torque, standpipe pressure, tong line pulling, SPM1&2&3; rotary RM and mud return flow.
•Components and features:
It is consisted of screen with gauges, data acquisition box (DAQ), sensors, background workstation, power supply unit and system program.
The monitor adopts screen with gauges to show data. The screen can be embedded in a bigger console or work as an independent one. It is small and compact, and fits well. The DAQ can be installed in electric-controlled room or in dog’s house according to real conditions on site. Power supply unit concludes industrial switch power-source and on-line UPS.
The background industrial PC workstation is used to record and deal the data in remote area and showing data in digits, curves and analog charts. It also restore, review and print data in curve and reports and preset alarm limits. The Chinese screen can switch to English.
The system is EX designed with anti-electromagnet, water-proof and anti-seismic. The technology of industrial bus makes the system run stable in complex conditions.
