【摘要】：石油在管道输送过程中的泄漏事件时有发生,会造成自然资源的浪费、环境污染等问题。更为严重的是泄漏事件直接威胁周边广大人民群众的生命和财产安全。因此能够及时、准确地发现管道输送的石油产品泄漏、泄漏位置及泄漏量具有极其重要的意义。本文以吴延线原油管道为背景,详细地分析了吴起—延炼原油管线的工艺需求,设计了一套全自动在线检测泄漏检测与定位系统。该系统以负压波信号检测定位方法作为理论基础,能够实时运行检漏系统的总模块,完成系统各个硬件模块的搭建,建立数据采集、数据远程传输技术、管道的基础数据综合分析的自动检测系统,实现现场设备控制、趋势分析、报警管理、操作记录、报表打印等功能。本文结合现场生产实际和相关参数从软件及硬件两个方面完成系统的整体构架。硬件方面基于数据采集设备来采集现场压力、流量、温度信号等数据,通过局域网实现数据通讯;软件方面利用Citect组态软件开发软件界面,并通过其调用泄漏检测报警、定位模块、共同组成泄漏检测系统。经过调试运行,该系统适用于原油长输管线的泄漏检测,检测定位灵敏准确,对快速突发性的泄漏适用性很强,能够为原油管道运输提供实时监控分析,满足长输管线的管理需要,为管道的安全运行提供了保证。
[Abstract]:The leakage of oil in pipeline sometimes causes waste of natural resources and environmental pollution.What is more serious is that the leakage directly threatens the lives and property safety of the surrounding people.Therefore, it is of great significance to find the leakage, leakage location and leakage quantity of petroleum products transported by pipeline in time and accurately.In this paper, based on the oil pipeline of Wuyan line, the technological requirements of Wuqi-Yanling crude oil pipeline are analyzed in detail, and a set of automatic on-line leak detection and location system is designed.Based on the method of detecting and locating the negative pressure wave signal, the system can run the main module of the leak detection system in real time, complete the construction of each hardware module of the system, establish the technology of data acquisition and remote data transmission.The automatic detection system for comprehensive analysis of basic data of pipeline realizes the functions of field equipment control, trend analysis, alarm management, operation record, report form printing and so on.In this paper, the overall framework of the system is completed from the aspects of software and hardware, combined with the field production practice and related parameters.Hardware based on data acquisition equipment to collect field pressure, flow, temperature signals and other data, through the LAN to achieve data communication, software use Citect configuration software development software interface, and through its call leakage detection alarm,Location module, together with a leak detection system.After debugging and running, the system is suitable for leak detection of long distance crude oil pipeline, the detection location is sensitive and accurate, and it has strong applicability for rapid and sudden leakage, which can provide real-time monitoring and analysis for crude oil pipeline transportation.Meet the management needs of long-distance pipeline, and provide a guarantee for the safe operation of pipeline.
