【摘要】：实时监测油气田井口的数据对于提高油井开采寿命和开采效率有着非常重要的意义。传统油井开采都处在环境相对恶劣,交通不便,人烟稀少的地区,且采用人工的方式进行现场巡井,不仅效率低下,而且花费巨大。同时现阶段油气田井口设备多采用分离式安装在控制箱内,造成众多弊端。随着现代物联网技术、微处理器技术的快速发展,同时针对当前油气田油井数量快速增加的问题,数字化油田建设势在必行。针对目前油气田井口监测存在的一些问题,本文设计出一种油气田井口远程监控系统。系统主要由现场采集设备、前端监控终端、井场上位机、监控中心几部分组成,其中前端井口监控终端RTU是整个系统的核心,采用德州公司开发的一类具有16位总线带FLASH的单片机MSP430F149作为主控制器,监控终端RTU主要实现对现场设备采集到的信息进行接收,经过处理、存储,通过RS485总线或者RJ45通信将数据发送给井场的上位机,监控终端RTU和上位机之间采用工业标准的Modbus协议进行通信,然后通过油田专用网络传给监控中心进行实时监测。系统软件部分的设计采用集成软件开发平台IAR Embedded Workbench,开发环境成熟,模块化设计思想。最后设计出的RTU运行稳定可靠,能够实时监测到数据,满足各项指标要求。本系统的应用可以有效监控井口采集到的数据,对井场突发的情况及时作出应变处理。系统不仅可以提高油气田的管理效率,降低工人的工作量,而且可以提高油井生产效率,减少生产成本,增加原油的产量。本系统具有一定的实用性和社会价值,是油气田数字化建设的有效选择。
[Abstract]:It is very important to monitor the wellhead data of oil and gas field in real time to improve the recovery life and efficiency.The traditional oil well exploitation is located in the area where the environment is relatively bad, the transportation is inconvenient and the people are few, and it is not only inefficient, but also costly to carry out the on-site inspection by artificial method.At the same time, the oil and gas field wellhead equipment is usually installed in the control box, which causes many malpractices.With the rapid development of modern Internet of things and microprocessor technology, it is imperative to construct digital oil field in view of the rapid increase of oil and gas wells.Aiming at some problems existing in wellhead monitoring of oil and gas field, a remote monitoring system for wellhead of oil and gas field is designed in this paper.The system is mainly composed of field acquisition equipment, front-end monitoring terminal, well field host computer and monitoring center. The front-end wellhead monitoring terminal RTU is the core of the whole system.A kind of MCU MSP430F149 with 16-bit bus with FLASH developed by Texas Company is used as the main controller. The monitoring terminal RTU is mainly used to receive, process and store the information collected by the field equipment.The data is transmitted to the host computer in the well field through RS485 bus or RJ45 communication. The communication between the monitoring terminal RTU and the host computer is carried out by using the industrial standard Modbus protocol, and then transmitted to the monitoring center through the oil field special network for real-time monitoring.The system software design adopts the integrated software development platform IAR Embedded Workbench, the development environment is mature, the modular design idea.Finally, the designed RTU is stable and reliable, which can monitor the data in real time and meet the requirements of every index.The application of this system can effectively monitor the data collected from the wellhead and deal with the unexpected situation in time.The system can not only improve the management efficiency of oil and gas fields, reduce the workload of workers, but also improve the production efficiency of oil wells, reduce production costs and increase the production of crude oil.This system has certain practicability and social value, and is an effective choice for oil and gas field digitization construction.
