[Abstract]:In the process of oil production, the application of multiphase flow metering and remote monitoring technology can accurately understand the production changes of oil and gas wells, carry out production analysis, and reasonably control and coordinate the production process. It can meet the actual demand of increasing production and increasing efficiency and production management in existing oil and gas fields. However, the problems of high cost, large amount of construction and installation, and high cost of maintenance in the later stage of oil well remote monitoring and control system have resulted in the slow application and low coverage rate of the remote monitoring and control system for oil wells. In view of the problems and shortcomings in the practical application and popularization of the existing oil well multiphase metering and remote monitoring system, combined with the latest development of embedded technology, A design scheme of distributed multiphase measurement and remote monitoring system for oil wells based on embedded technology is presented. According to the characteristics of the field multiphase flow separation device, the field data acquisition and processing part of the whole system is divided into three main modules: the monitor room metering data display terminal, the front-end separator data acquisition terminal, and the multi-well selection valve group controller. The short range ZigBee WLAN technology is used to realize the data transmission between the field separation metering device and the monitoring room. The metering data of each measuring station is sent to the remote data center through GPRS, and the data center makes unified analysis and processing. The system makes full use of the advantages of low cost and high stability of ZigBee technology, remote transmission of GPRS technology and long term on-line, and constructs a centralized management system for oilfield measurement data management and distributed query. Remote transmission, web publishing and other functions. The STM32 microcontroller based on Cortex-M3 and the open source uC- OS-II real-time operating system are used to design and implement the front-end separator data acquisition terminal (GPRS DTU) and the multi-well selection valve group controller. The S3C6410 processor based on ARM11 and Android operating system are used to design and implement the metrological data display terminal. The practical application of Android system in oil field multiphase measurement and monitoring is realized, including hardware design and implementation, transplantation of operating system, development of bottom driver, development of upper application program and system debugging. Field experiments show that the system can complete the functions of data acquisition, information retrieval, data query, report generation and so on. The system has been greatly improved in several aspects, such as reducing the equipment cost, simplifying the installation program of hardware and software of the equipment, facilitating the later maintenance, enhancing the versatility of the module, and so on. This will have a positive effect on the oil well multiphase metering and remote monitoring system popularizing in a wide range of oilfields, at the same time, it will greatly speed up the process of oil field transformation from our country's oil field to digital information oil field.
