天然气管网数字化中的网络应用

摘要

目前各石油石化企业在进行油气田、长输管道数字化的同时,也在探索GIS更深层次的应用。网络分析是GIS空间分析重要的手段。阐述了网络分析的基本原理和实现方法,以及天然气管网的几何网络和逻辑网络组成。结合天然气企业生产管理业务,描述了基于逻辑网络的网络分析如何实现工艺流程图生成、流程调度模拟、开关阀分析等,并提出深化网络分析的设想。%With the implementation of digital in the oil gas field and long distance pipeline transportation, the petroleum and petrifaction enterprises are exploring further deep application for GIS. Network analysis is an important space analysis method for GIS. The basic principle and methods of network analysis is described, as well as the buildup of the geometry network and logical network for natural gas pipeline network. Combined with the production and management of natural gas enterprise, the related method on how to produce process flow chart, and how to simulate flow control and switching valves analysis using logical network is described. And the scheme on how to deepen the application of network is put forwards.
