摘要
国外油气管道的详细信息对我国油气管道建设及运营具有重要的参考意义。鉴于国外该方面的资料多属机密,通过卫星照片对其研究不失为一种新的方法。目前通过Google Earth可以获取免费的卫星照片,且其本身带有查询经纬度、海拔及拍摄日期等功能,是很好的研究工具。在卫星照片上对所研究的管道进行判读识别进而定位后,可以获得管道的详细路由、各站场或阀室的具体位置、站间距、并行敷设管道的间距、河流的穿跨越方式、站场的总图布局、动力设备的驱动型式及数量、相邻储罐的间距等信息。受限于卫星照片的获取以及清晰度等影响,部分管道的研究可能会受到限制,甚至无法进行。国内掌握管道信息的从业人员切忌将管道数据标注于Google Earth等国外软件上,以防存在后门程序导致泄密事故。
Foreign information related to oil and gas pipelines has important reference significance to domestic construction and operation of oil and gas pipelines.Because most of such foreign information is confidential,free satellite photos can provide a new method for obtaining and researching information on foreign pipelines.Satellite photos can be obtained freely from GoogleEarth,which is a very good tool with such functions as inquiry of altitude,latitude and longitude and photos shooting dates.Such information on pipelines can be obtained from satellite photos as pipeline routes,locations of stations or valve vaults in pipelines,spacing between pipeline stations,spacing between the parallel pipelines,river crossing or overhead crossing manners,plot plans of stations,number and drive types of power equipments,and spacing of oil tanks and so on.However,due to limited acquisition and resolution of satellite photos,researches on some pipelines may be limited and even can not be conducted.In particular,any domestic pipeline research staff is required to avoid by all means inputting important pipeline information in such foreign online software as GoogleEarth in order to avoid that possible backdoors result in letting out any secret.
