The paper summarizes the experience of using wireless high-speed communication channels at oil and gas fields. Due to the constant increase in the volume of transmitted information when monitoring oil and gas production processes, the existing communication channels created in the early 90s of the XX century became insufficient. There is an urgent need to replace the old fleet of VHF radio stations and create new high-speed communication channels. Currently, there are two ways to organize high-speed communication channels: fiber-optic lines and broadband access. The article discusses the advantages and disadvantages of these methods. The wireless technologies WiMAX, WiFi are described. Their comparative characteristics are given.
Design and construction of high-speed communication channels in Udmurtneft JSC since 2010 is presented. This enterprise has developed standard schemes of communication systems, equipment placement in premises and subscriber stations; specifications of the necessary equipment for solving automation problems were drawn up. Data from sensors installed on production wells, information on the state of electric drives of borehole pumps, parameters of group metering units, pressure manifold blocks, and signals from the capacity of industrial effluents, all of this are transmitted via the broadband radio channel to the workstation of the oil field dispatcher. Calculations of radio channel profiles for base and subscriber stations have been performed. Since 2011, the broadband access system has been successfully operating at the Mishkinskoye oil field, since 2012 - at Gremikhinskoye, Listvenskoye and Kiengopskoye. The measures for the construction and modernization of the technological communication network are described. The article describes the technical maintenance of the broadband access system at Udmurtneft JSC, and the equipment providing hardware implementation of high-speed radio access. The system operates under the control of the WANFlex operating system and is currently being installed at the oil and gas fields of Udmurtneft JSC.
