Configuration and operation status of cross-border metering stations in China–Russia Eastern Gas Pipeline

As a large-scale cross-border gas transmission pipeline, the technology and management level of the trade metering station of China–Russia Eastern Gas Pipeline will directly affect the economic interests of China and Russia. The natural gas trade metering of China–Russia Eastern Gas Pipeline is completed by three metering systems, of which the main metering system and the verification metering system are installed in Russia's Blagoveshchensk metering station, and the comparison metering system is installed in China's Heihe metering station. The operating parameters of the two metering systems of Russia are transmitted to Heihe metering station in real time, enabling an all-round monitor to the three metering systems in China and Russia. The settled volume of trade can be finally determined by comparing the measurement results of the three systems. As per the gas quality parameters stipulated in the Natural gas metering agreement signed by China and Russia, the gas quality analysis device shall be equipped at the metering stations of both countries, and the test results of all gas quality analysis device at Russian metering stations shall be transmitted to Heihe metering station in real time. In addition, intelligent construction in Heihe metering station not only reduces the influence of metering station control system debugging on metering system, but also realizes intelligent remote diagnosis and process changeover. Based on the current operation status of metering stations, the following suggestions are put forward. ① The automation logic test should be added in the running process, and automation professional companies should be collaborated to conduct tests on the use of the system, so as to simplify the control logic and improve the stability of the system. ② The training and testing of technical personnel should be emphasized in order to improve the operation and management of the metering station.
