为了适应新体制下成品油管网的管理模式,构建服务型管道体系,实现批次跟踪技术的通用性,从国家石油天然气管网集团有限公司体制出发,探讨了成品油管道批次界面跟踪相关技术。首先,从信息层面,规范了油品批次编码规则以及作业术语,以便于进行推广应用;在开发环境方面,在线实时跟踪是提高成品油管道批次界面跟踪软件(简称跟踪软件)精准度的有效方法,在国产SCADA系统上开发跟踪软件是最佳途径;在技术方案设计方面,确定了界面跟踪应采取50%浓度点(体积分数)的跟踪方式,进行了跟踪软件的功能及流程设计;在面临的关键问题方面,对批次跟踪的准确性、校准与误差修正方面进行了分析,并用现场应用效果进行了实例验证。从数据体系、输油工艺、模型系数3个方面对跟踪软件的定制化与通用性进行了论述,提出了从软件功能层面出发的跟踪软件界面设计思路。研究成果可为成品油管道批次界面精确跟踪技术的研究、成品油管网操控新模式的开启奠定基础。(图4,表3,参22)

In order to adapt to the management mode of the products pipeline network under the new system,set up a service-oriented pipeline system and make for the universality of batch tracking technology,a discussion was made about the products pipeline batch interface tracking technology under the PipeChina system.First of all,the oil batch coding rules and operation terms were standardized from the perspective of information level,which is favorable to the popularization and application.In terms of the development environment,it was considered an effective way to apply online real-time tracking to the accuracy improvement of products pipeline batch interface tracking software(hereinafter referred to as the tracking software),as well as the best way to develop the tracking software on the domestic SCADA system.In respect of technical scheme design,an interface tracking method with 50%concentration point(vol%)was determined and a design was made to the function and flow of tracking software.In response to the key challenges,the accuracy,calibration and error correction of batch tracking were analyzed and verified by the field application results.The customization and universality of the tracking software were discussed from three aspects:data system,oil transportation technology and model coefficient.As a result,an idea was proposed to design the tracking software interface from the software function level.Generally,the research results lay a foundation for the research on accurate products pipeline batch interface tracking technology and the opening of a new control mode of products pipeline network.(4 Figures,3 Tables,22 References)
