Abstract: Digital oilfield has been under rapid development in recent years. It is of great urgency for oilfield enterprises to improve productivity and bring about sustainable development. PetroChina Dagang Oilfield Company started to optimize and simplify the surface system from 2004. It made breakthroughs in traditional measurement and water-distributing pattern, digitalize oil and water wells, used the software for metering oil and established the “Gangxi model” by keeping water distribution reasonable. In accordance with the requirements on standardization of surface engineering in 2008, the company fully completed upgradation and renovation for digitalization of oil and water wells, digitalization of pipelines, stations and tank fields, bringing pipelines under on-line monitoring and automatic alarming. In 2013, the constructed the unattended digitalized stations and fields of medium and small sizes and established the “Wangxuzhuang model”, modernizing management of stations and fields. Meanwhile, it formulated and released the related norms and specifications and perfected the operational management system. In the efforts for digitalization of oilfields, large-scale application of Internet of things technology and information technology led to reduction of surface construction scale, conversion of production mode, optimization of labor organization, and remarkable improvement of management efficiency, providing powerful support for effective development of old oilfields, improvement of quality and efficiency for oilfield enterprises and sustainable development.

摘要： 近年来数字油田建设快速发展，油田企业对如何提高生产效率、实现油田可持续发展需求迫切。中国石 油大港油田公司自2004 年开始地面优化简化工作，突破传统的计量及配水方式，开展油水井数字化建设，实现软件 量油、稳流配水，形成了“港西模式”；2008 年按照地面工程标准化建设要求，全面完成油水井数字化升级改造， 同步开展管道、站库数字化建设，实现了管道实时在线监测、自动报警；2013 年开展中小型场站无人值守数字化建设， 建成“王徐庄模式”，实现少人值守、集中监控、站库管理现代化；同步制订发布标准规范，建立健全运行管理体系。 数字油田建设中，物联网技术和信息技术的规模应用，实现地面系统建设规模缩减、生产方式转变、劳动组织优化、 管理水平和管理效率显著提高，为老油田效益开发、油田企业提质增效、可持续发展提供了有力支撑。
