Abstract: To address the technical challenges featured as deep burial depth, complex geological conditions, low development efficiency, and high difficulty in safety management in Qingcheng shale oil reservoirs in the Ordos Basin, guided by the goal of cultivating new quality productive forces, this study integrates new-generation of information technologies including artificial intelligence, Internet of Things, cloud computing, and large models to innovatively establish a "416" technology management system for digital-intelligent development of shale oil. This system is based on four technical guarantees covering intelligent perception, highly reliable industrial networks, all-domain data governance, and industrial control security encryption as its underlying foundation. It uses a full lifecycle Internet of Things cloud platform as its core middle platform, and six core business scenarios such as intelligent on-site operation control, intelligent analysis of technical management, intelligent control of production and operation, intelligent collaboration of business and office management, intelligent early warning of safety and environmental protection, and intelligent control of green and low-carbon development as its implementation carriers. It has achieved digital transformation of the entire process and all elements of shale oil development. On-site application results show that this system enables the production site in Qingcheng shale oil to achieve a 100% digital coverage, improves the reservoir performance analysis efficiency by 30%, enhances the efficiency of thermal cleaning by 60%, reduces the staffing of joint stations by 85%, and lowers the total cost of shale oil to 47.7 USD/bbl, with the workforce per million tons controlled within 200 personnel (one-tenth of that of conventional oil fields). This system supports the establishment of China's first 2-million-ton shale oil development demonstration base, providing a replicable and scalable technical model for the large-scale and efficient development of shale oil in China.
