Expert Review Comments:
International advanced level. Focusing on continental shale oil reservoirs, this project innovatively developed a “temperature–pressure–stress–fluid” multi-field coupled diagenetic simulation device, systematically revealing the synergistic evolution mechanism between organic matter and minerals and proposing the “mineral–organic matter complex” theory, filling a gap in the continental shale oil accumulation theory.
The project constructed a full-scale pore intelligent characterization system, achieving high-precision automated identification and quantitative evaluation of pore structures, significantly enhancing sweet spot prediction and reservoir fine evaluation capabilities. The achievements have been successfully applied in multiple shale oil blocks, generating hundreds of millions of yuan in economic benefits, driving theoretical innovation and technological progress in shale oil exploration and development, and providing a significant model and leadership for the efficient development of China’s unconventional oil and gas resources.

Main Innovations:

This project has achieved three core innovations:

① Independently developed a “temperature–pressure–stress–fluid” multi-field coupled diagenetic simulation device, realizing dynamic reproduction of the entire shale diagenetic process and supporting reservoir sweet spot prediction;

② Proposed the “mineral–organic matter complex” theory, for the first time revealing at the molecular level the synergistic interactions between organic matter and minerals and their regulatory mechanism on the source–reservoir system, advancing research on shale oil accumulation mechanisms;

③ Created a pioneering full-scale pore intelligent evaluation technology, integrating multiple characterization methods to achieve high-precision automated analysis of pore structures, improving identification efficiency by more than threefold.
The project’s results provide original theoretical and core technological support for fine shale oil exploration, reservoir evaluation, and green, low-carbon development in China.

Main Uses and Technical Principles:

The technologies developed in this project are mainly used for fine exploration, potential evaluation, and sweet spot prediction of shale oil reservoirs, guiding efficient development and green extraction, enhancing the utilization efficiency of domestic unconventional oil and gas resources, and supporting energy security and low-carbon development.
The technical principles include three aspects:
(1) The independently developed “temperature–pressure–stress–fluid” multi-field coupled diagenetic simulation device dynamically reproduces the full diagenetic evolution process of shale under high temperature and pressure, revealing the reservoir formation mechanism;
(2) The “mineral–organic matter complex” theory elucidates at the molecular level the multiple interactions between minerals and organic matter and their regulatory effects on hydrocarbon generation rates and reservoir development;
(3) The original full-scale pore intelligent evaluation technology integrates multiple analytical methods to realize high-precision automated characterization of pore structures, providing original technical support for fine shale oil exploration and green development.
