Cloud computing as a new service model has been gradually extended from the traditional IT industry to traditional industrial domains, but research on and the application of the digital oilfield cloud platform remain lacking. By introducing the reference frame of the integrated platform of oil enterprises at home and abroad, we adopt the design method of the integrated architecture of enterprises and the metadata-based object-oriented development model based on the design concept of cloud computing to identify efficient and inexpensive information platform solutions. Research is conducted on a cloud data service management system for digital oilfields. The overall structure of the cloud platform for digital oilfields is divided into five layers of infrastructure, data resources, functional services, applications, and terminal access and into two support subsystems, namely, cloud information specifications and standards and cloud service management platform. The cloud data service platform is generalized as an architecture with "a center, three layers, two buses, and two sub-functional systems." Results show that the cloud data management system performs the four core functions of model, data bus, data service bus, and data quality control management. Furthermore, integrating cloud computing into the transformation and upgrading of traditional industries is feasible and applicable to other related fields.
