IRZ TEK CENTRALIZED CONTROL SYSTEM KDU IRZ Function Remote monitoring and control of oilfield equipment in order to improve the production process, reduce costs and to improve efficiency of oil production. Description The Centralized Control System has hierarchic threelevel structure. The lower level comprises primary measuring transducers and actuating mechanisms involved into the production process and control stations for local automatic equipment (control stations for electrical submersible pumps, sucker-rod pumps and group metering stations). The middle level comprises production process control stations, i.e. IRZ-501-01, 08, 02, 16, that receive data from sensors and primary measuring transducers of the lower level and transfer the data to a master controller. The master controller represented by production process control stations IRZ 501-04, 23, 26, is an intermediate link of the system. It optimizes scanning of oilfield units and transfers all data via communication equipment to a control room. The upper level comprises an operator s work-bench and database server with software installed which receives and archives all data on process parameters (pressure, temperature, flow rate), security alarm system and system voltage presence. When any object is disconnected, the operator receives a signal indicating the disconnection and description of the cause. For analytical data processing, the reports are forwarded via web interface. The system features flexible routing when various communication equipment is used to transfer data, i.e. radio modems within the frequency range of 433 434 MHz and 146 174 MHz, GPRS-modems, wide-band access systems for high-speed data transmission via radio channels, Ethernet networks, etc. SPECIFICATION The specifications depend on the type and configuration of the oil field Parameter Value Maximum number of connected units 10000 Communications range, km up to 100 Network protocols MODBUS-RTU, MODBUS-TCP, DNP3 34 24-hour technical support service tel. 8-800-100-63-93 Toll-free within Russia
