Abstract:

Remarkable achievements have been attained in the digital transformation and intelligent construction of China’s underground gas storage (UGS) facilities, shown as follows. (1) Key technologies, including the hydrocarbon reservoir-wellbore-pipeline network integrated coupling simulation and digital twins, have been developed for the intelligent construction of UGS facilities. (2) An intelligent cloud platform framework for UGS facilities has been established in the mode of data + platform + application. This platform fully utilizes new-type infrastructure like data center (DC), Internet of Things (IoT), and Industrial Internet of Things (IIoT), aiming to meet the demand for the management, research, production, and services of various business segments. (3) The intelligent construction of UGS facilities has led to the R&D of a UGS information management platform, UGS integrated management platform, decision support system using digital twin-based integrated simulation, and a digital platform covering the entire lifecycle of UGS facilities. The future intelligent construction of UGS facilities will focus on the development of new technologies, encompassing digital twin technologies for geological bodies, high-precision modeling, dynamic visual representations, intelligent operation, real-time intelligent risk warning, industrial software localization, and technologies based on the Beidou Navigation Satellite System (BDS) and satellite internet.
