Expert Review Comments:
International advanced level. This project innovatively constructs an IoT cloud platform for shale oil, integrating cloud computing, big data, and artificial intelligence technologies to form a digital management system covering all business segments such as production, technology, safety, and operations. Through cloud-edge collaboration and intelligent closed-loop operation, it realizes real-time monitoring, data mining, intelligent analysis, and decision optimization in the production process, significantly improving management efficiency and safety levels. The project has been successfully applied to more than 400 wells in the Qingcheng Oilfield, promoting the digital and intelligent transformation of shale oil development. It has achieved excellent economic and social benefits and provides a replicable technological model and practical benchmark for smart oilfield construction.

Main Innovations:

This project innovatively developed the first integrated, comprehensive, full-service IoT cloud platform for shale oil. It integrates production, technology, safety, and operations into multi-service, full-cycle intelligent management modules, pioneering the first industrial control IoT system in the industry based on cloud architecture. The integration of digital intelligence drives transformation in shale oil management and enhances efficiency. Intelligent monitoring and analysis technologies unlock data potential and stimulate high-quality productivity; the upstream and downstream linkage control of processes deepens underlying logic and interlock control; and the adoption of cloud-edge collaborative intelligent closed-loop management technology optimizes organizational structure and management processes.

Main Uses and Technical Principles:

Main Uses:
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 and new materials, engineering technology, and equipment manufacturing.

Technical Principles:
The platform adopts advanced technologies such as cloud computing, big data, artificial intelligence, and cloud-edge collaboration, integrating real-time acquisition, edge-side closed-loop interlock control, and intelligent decision-making functions. It forms an all-round intelligent management and control platform for oil and gas business scenarios, featuring production monitoring, multi-parameter linkage alarm, intelligent diagnosis, early warning, data-driven analysis, and intelligent integrated reporting. The platform supports multiple data access protocols and storage formats, with personalized customization and multi-system interaction capabilities, helping users establish a full life-cycle management model characterized by “process integration, information fusion, stage supervision, and data interconnection.”

Technical Applications:

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

In addition, the launch of Changqing Oilfield’s first full life-cycle shale oil IoT cloud platform has enabled full-business data sharing, autonomous and stable well operation, unmanned and stable station operation, and intelligent and safe pipeline operation, creating an intelligent oilfield with real-time perception, intelligent analysis, and automatic control. With the one-million-ton operation controlled by fewer than 200 workers, the per capita crude oil output contribution reached 4,869 tons per year, ranking first in Changqing Oilfield and third among 98 oil production units in CNPC’s 2024 annual benchmarking evaluation.

As oil and gas exploration continues expanding toward broader, deeper, and more complex reservoirs, Changqing Oilfield accelerates resource transformation through theoretical and technological innovation. It will continue 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 technology will be gradually promoted to the Fifth Oil Production Plant, the Twelfth Oil Production Plant, the Second Gas Production Plant, the First Oil Transportation Division, and deep coalbed methane units, ultimately forming a set of replicable, applicable business scenario models and intelligent construction achievements.
