Expert Review Comments:
International advanced level. This project innovatively developed an IoT cloud platform for shale oil, integrating cloud computing, big data, and artificial intelligence technologies to establish a digital management system covering all business segments, including production, technology, safety, and operations. Through cloud-edge collaboration and intelligent closed-loop operation, the system achieves real-time monitoring, data mining, intelligent analysis, and decision optimization of the production process, significantly improving management efficiency and safety standards.
The project has been successfully applied to over 400 wells in the Qingcheng Oilfield, promoting the digital and intelligent transformation of shale oil development. It has achieved remarkable economic and social benefits, providing a replicable technical demonstration and practical model for the construction of smart oilfields.

Main Innovations:

This project innovatively developed the first integrated, comprehensive, and full-service shale oil IoT cloud platform, which integrates multiple businesses such as production, technology, safety, and operation, and a full cycle digital intelligent management module. It marks the first time in the industry to build an industrial control IoT system based on cloud architecture, promoting shale oil management reform and efficiency improvement through the integration of data and intelligence. Intelligent monitoring and analysis technology has tapped into the potential of data and stimulated high-quality and efficient momentum; The upstream and downstream linkage control of the process flow has deepened the underlying logic and interlocking control; By adopting cloud edge collaborative intelligent closed-loop operation management technology, the organizational structure and management processes have been optimized.

Main Uses and Technical Principles:

Main application：The IoT cloud platform has broad application potential and strong adaptability, and can be deeply applied in the fields of oil and gas new energy, refining new materials, engineering technology, and equipment manufacturing. 

Technical principle：Advanced technologies such as cloud computing, big data, artificial intelligence and cloud edge collaboration are adopted to integrate real-time collection, edge computing, closed-loop interlocking control, intelligent decision-making and other functions, forming a comprehensive intelligent management and control platform with production monitoring, multi parameter linkage alarm, intelligent diagnosis and early warning, data intelligent analysis, intelligent comprehensive report and other oil and gas business scenarios. The platform supports a variety of data access protocols and storage formats, has personalized customization development and multi system interaction capabilities, and assists users to establish a full life cycle management mode of "process connection, information integration, link supervision, and data interconnection"

Technical Applications:

Changqing Oilfield regards shale oil as an important replacement resource for large-scale and efficient production growth. It has conducted in-depth theoretical research, intensified technological innovation, and continuously strengthened management innovation. After discovering a shale oil field with proven geological reserves exceeding one billion tons, Changqing built the first national shale oil development demonstration zone with an annual capacity of one million tons, pioneering a new pathway for large-scale and efficient development of unconventional oil and gas resources.

Moreover, the launch of Changqing Oilfield’s first full life-cycle shale oil IoT cloud platform has realized full-business data sharing, autonomous and stable operation of oil wells, unmanned and steady operation of field stations, and intelligent and safe operation of pipelines. It has created an intelligent oilfield featuring real-time perception, intelligent analysis, and automatic control. Labor efficiency has been significantly improved, maintaining the one-million-ton operation scale with fewer than 200 workers, and achieving an average crude oil production contribution of 4,869 tons per person per year—ranking first in Changqing Oilfield and third among 98 oil production units in CNPC’s 2024 benchmarking evaluation.

As oil and gas exploration expands toward broader, deeper, and more complex reservoirs, Changqing Oilfield continues to accelerate resource conversion through theoretical and technological innovation. It will persist in tackling key technologies for the efficient development of unconventional resources, breaking through the limits of low-permeability, ultra-low-permeability, and unconventional resource exploitation. By establishing a technological innovation hub for low-permeability and unconventional oil and gas, the production scale is expected to reach two million tons by the end of the “14th Five-Year Plan.” The platform will gradually be promoted to the Fifth Oil Production Plant, Twelfth Oil Production Plant, Second Gas Production Plant, First Oil Transportation Division, and deep coalbed methane units, forming a set of replicable and applicable business scenario models and intelligent construction achievements.
