The Research Of A Device Used For Metering Heavy Oil Online

With the progress of the development of science and technology, various needs of the oil-field is developing, the oil well metering device,who have powerful functions, high level of automation is more and more attention.The traditional methods of separating measurement, measures after oil water separation, while the technology is mature, the measuring accuracy is high, but due to its characteristics of heavy oil, it is difficult to measure, if still adopts the traditional way of measuring, first will cause the higher input,Second is not good to solve the problem of heavy oil metering, so looking for a kind of online real-time metering device is very necessary.The papers collected from domestic and foreign related research achievements of oil well measurement and technical data, according to the oil field of thick oil actual situation in our country present design, especially high waxy of heavy oil in the north,put forward the new type oil well the idea of separation of online real-time measurement. After the analysis of oil well metering system research, puts forward a set of practical oil well metering system. From simple skip metering, determine the design scheme is given priority to with skip weighing metering, and designed the structure diagram of the well separation measurement, involving the well study the separation of metering system to conduct a comprehensive analysis of argument, the selection and working principle of each part is determined, gas measurement, temperature measurement, the solution of moisture content determination, weighing solutions. Finally design weighing metering system using of Siemens S7-series PLC system to remote control, data storage, computation, etc.Through Comparing with the traditional two phase test separator, three phase separator, the measuring way of heavy oil direct weighing, not only improves the measuring accuracy, and combining with PLC system, truly ruly realized the remote monitoring, is one of the oil production industry gathering pattern breakthrough, in order to improve the labor productivity, reduce the labor intensity of workers, as well as saving investment provides a strong support.Through this paper research work, not only for heavy oil metering device and provides the theory basis for further research, but also to other types of system research to provide certain reference.
