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.
