长输管道完整性管理GIS数据模型研究

随着我国长输管道建设规模的不断扩大,管道运营过程中出现的安全问题逐渐成为行业内部乃至整个国家和社会所关注的焦点。针对上述问题,业内专家提出的以G IS为其实现手段,对管道进行完整性管理,是目前解决管道运营中的安全问题可采用的一种较好的方法。采用完整性管理方法,首先需要对管道数据进行建模,把管道的设计资料、竣工资料、检测数据以及设备信息等统一的用空间数据库来管理。本文首先分析了目前国际上现有的多个管道数据模型,然后参考国际上管道完整性管理的理论与方法,同时结合国内管道完整性管理的实践经验,阐述了设计适合我国管道工业的长输管道数据模型的具体过程。在模型的应用上,主要体现在建立管道完整性管理信息系统。该系统充分利用了模型中提供的各类信息,在此基础上,集中开发了线路管理模块、风险/完整性评价模块、站场管理模块等。实践证明,本文提出的管道数据模型在我国管道完整性管理中具有很高的应用价值。

Data Model for the Realization of Long-Distance Pipeline Integrity Management and Its Application

Along with the constant development and expansion of the industry of long-distance pipeline construction in China,pipeline security has gradually become a focus of the country and the whole society.In view of this,some experts proposed pipeline integrity management combined with techniques of GIS,which has been considered as a well-adapted solution.In this approach firstly it needs data modeling and then all data such as pipeline design,as-constructed,inspection data,et al.are altogether and efficiently managed within defined spatial database.In this paper,the author first compares several worldwide currently existing pipeline data models,and then explains in detail the designing process of the long-distance pipeline data model that suits our pipeline industry,referring to the international pipeline integrity management theories and methods as well as domestic practical experience.Finally,the author elaborates the whole process of establishing the pipeline integrity management information system by dint of techniques of geographic information system and spatial database.In the latter process of model application,the pipeline integrity management information system is established then,which makes full use of all types of information provided by the data model and successfully develops the LineLoop management module,risk / integrity evaluation module and site management module.Practice has proved a high potential for applications of this proposed pipeline data model in China pipeline integrity management.
