【摘要】：在石油开采过程中，应用多相流计量与远程监控技术可以准确地了解油气水井生产变化情况，进行生产分析，合理地控制和协调生产过程，，可满足现有油气田的增产增效和生产管理的实际需求。但当前油井远程计量监控系统普遍造价高、施工安装工程量大、后期维护成本高等问题，导致当前油井远程监控系统推广应用缓慢，覆盖率低。 针对现有油井多相计量与远程监控系统在实际应用推广过程中遇到的问题和不足，结合当前嵌入式技术的最新发展，提出一种基于嵌入式技术的分布式油井多相计量与远程监控系统设计方案。 根据现场多相流分离装置的特点，将整个系统的现场数据采集与处理部分划分为三个主要模块：监控室计量数据显示终端、前端分离器数据采集终端、多井选井阀组控制器。现场分离计量装置与监控室之间采用短程ZigBee无线局域网技术实现数据传输，各计量站的计量数据则通过GPRS发往远端数据中心，由数据中心做统一分析处理。该系统充分利用了ZigBee技术的低成本高稳定性以及GPRS技术的远程传输与长期在线的优点，构建了油田计量数据集中管理和分布查询的管理系统，整套系统具有数据采集、远程传输、网页发布等功能。 采用基于Cortex-M3的STM32微控制器搭配开源的uC/OS-II实时操作系统设计实现了前端分离器数据采集终端、GPRS DTU和多井选井阀组控制器。采用基于ARM11的S3C6410处理器搭配Android操作系统设计实现计量数据显示终端。实现了Android系统在油田多相计量与监控方面的实际应用，包括硬件设计与实现，操作系统的移植，底层驱动程序的开发，上层应用程序的开发和系统调试。 现场实验表明，系统能够完全实现数据采集、信息检索、数据查询、报表生成等功能。系统在降低设备成本、简化设备软硬件安装程序、方便后期维护、增强模块的通用性等几个方面有了很大的提升。这将对油井多相计量与远程监控系统在油田的大范围推广产生积极的作用，同时也会极大的加快我国油田向数字化信息化油田转变的进程。

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.
