油田管网应急指挥关键技术研究

采用分层叠加、坐标转换、穿孔管网关联阀门和地图数据分时修正技术构建了油田应急指挥系统,其中坐标转换技术实现了经纬度到西安80坐标的转换,为穿孔管网关联阀门定位事故点做好了准备;穿孔管网关联阀门技术通过管网与阀门之间的拓扑关系实现了管网与阀门之间的智能查询,完成对应急事件的处理;地图数据分时修正技术实现了地图文件的修正维护。通过应用这4种技术,在最短的时间内达到地图上事故点定位、关联到离事故点最近的阀门和调用应急响应预案处理事故管网的目的,解决了以往管网、阀门等基础设施的具体位置靠人工经验定位的问题,同时在对地图数据维护时,实现了地图数据的安全性和统一性。

Key Technology Research for Emergency Command in Oil Field Pipe Network

Having technologies of layered superposition, coordinate transformation, associating perforated pipelines with valves and the map data correction at various times adopted to construct the emergency command system for the oil field was implemented, in which, the coordinate transformation technology can achieve con-version of the latitude and longitude to the Xi′an 80 coordinate and this makes ready for locating the fault valve associated with perforated pipelines; through topological relationship between the pipeline and the valve, that of associating pipelines with valves can realize intelligent query and treatment of emergency incident;and that of the map data correction at various times can correct and maintain map files. The application of these four techniques can achieve the purposes like locating accidents at short time, actuating the valve nearest to the fault pipeline, calling emergency response plan and dealing with pipeline failure. This replaces the artificial experience in locating the fault pipelines and valves and realizes the security and the unity of the map data in map data maintenance.
