SENDOIL / Drilling instrumentation systemsSDZ2000 centralized electric-gauge drilling instrumentation
The SDZ2000 rig parameter monitor is an integrated electronic, computer-based, communications-based drilling instrument for electric rigs, mechanical rigs, ocean platforms and well repair machines. Drilling parameters such as hook suspension, turner twister, standpipe pressure, piston tailline pull, pump speed 1/2/3, turner speed, well-head slurry return volume can be monitored.
Overview:
The SDZ2000 rig parameter monitor is an integrated electronic, computer-based, communications-based drilling instrument for electric rigs, mechanical rigs, ocean platforms and well repair machines. Drilling parameters such as hook suspension, turner twister, standpipe pressure, piston tailline pull, pump speed 1/2/3, turner speed, well-head slurry return volume can be monitored.
• Composition and characteristics:
SDZ2000 consists mainly of plaque displays, data collection and processing boxes (DAQ units), sensors, back-office workstations, power supply systems, and specialized processing software.
The instrument is displayed in a typographical display, which can be integrated into a console in the drill room or embedded in an independent dashboard, with a simple, compact and compact structure, and is adaptable. The data collection box may be installed in the electrical control room or in the division drilling room, depending on the situation on the ground. The power supply system consists of industrial-grade switch and uninterruptible power (UPS online).
Back-office data are processed using industrial control computers as workstations to allow remote monitoring, synchronized display of variations in drilling parameters, with simulations, numbers, curves, medium and English switching, storage, playback, printing curves and reports, and alerting settings for the parameters.
The system uses blast-proof, electromagnetic interference-resistant, dust-resistant, water-resistant, anti-shock-resistant designs, and industrial field bus technology that can stabilize operations at complex drilling operations.
