一、     Recent research interests

Based on the scientific research projects of the National Natural Science Foundation, the Ministry of Science and Technology and petroleum and petrochemical enterprises, the team conducts in-depth research on deep geological processes, organic-inorganic interactions and oil and gas accumulation, aiming to expand new theories and methods of oil and gas accumulation under organic-inorganic interactions, and to enrich and improve the classical petroleum geology theory, providing scientific basis and guiding ideas for new resource exploration and development.

The team focuses on two main fields of scientific principles and fundamental applications.

A. Scientific principles - Organic-Inorganic Interactions.

The processes and mechanisms of deep crust-mantle organic-inorganic interactions on the deep carbon cycle, deep hydrocarbon and mineral enrichment, and the synergistic evolution of biology, environment, and climate in the early Earth and key geological periods need to be urgently explored, and the mechanisms of organic-inorganic medium interactions are not yet fully understood. This field aims to provide evidence and constraints for understanding the mechanisms of deep geological activities.

1) Effects of deep fluids and volcanic activities on palaeoclimatic and palaeoenvironmental changes, biological blooming processes, and organic matter enrichment.

2) Generation and alteration processes of hydrocarbons in deep hydrothermal organic-inorganic interactions.

3) Biological record of geothermal events in deep time sediments, reconstruction of palaeo-oceanic ecosystems and evolution of life.

4) Mechanisms of formation of geothermal resources and abiotic gas resources (H₂ , He, CO₂ etc.) under deep geological activities.

B. Fundamental Applications - Hydrocarbon Generation – Reservoir Formation Petroleum Accumulation.

In the context of multi-sphere interaction, deep hydrothermal fluids, as a link between the inside and outside of hydrocarbon-bearing basins, involve in the whole process of hydrocarbon generation, reservoir formation and petroleum accumulation by organic-inorganic interaction, but the time, intensity and scope of the interaction and the physicochemical processes and mechanisms remain unclear. This field aims to set the foundation for establishing a new theory of organic-inorganic complex hydrocarbon generation and reservoir formation and exploring the utilization of deep resources.

1) Hydrocarbon generation: Quantification and identification of deep fluid catalysis on the promotion of hydrocarbon production processes and enhancement of hydrocarbon production in different types of organic matter.

2) Reservoir formation: Study of physicochemical processes between deep fluid intrusion and sedimentary basin to explore reservoir formation mechanisms under different geological background and fluid action. Long-term safe storage of artificial CO₂ in geological bodies.

3) Petroleum accumulation: Tracing the generation process of oil and gas under deep fluid alteration, determining the possibility of separate accumulation of new associated resources (abiotic methane, H₂ , He, etc.) into reservoirs, and elucidating the differential control mechanism of different types of resource accumulation under different geological backgrounds.

三、 Research Team

The “organic-inorganic interaction” team continues to introduce cutting-edge theoretical and technical talents from home and abroad, and focuses on training a number of young talents, forming an international multidisciplinary team. The team has research experience and original data on oil and gas generation, organic-inorganic interaction, abiogenic gas formation, and deep hydrocarbon cycle mechanism. The team has hosted/participated in more than 10 projects of the Ministry of Science and Technology of the People's Republic of China and the National Natural Science Foundation of the People's Republic of China, mostly involving deep geological interactions. The team has proposed the theory of deep fluid organic-inorganic complex genesis earlier in China. The team is supported by the State Key Laboratory of Shale Oil and Gas Enrichment Mechanisms and Effective Development, which has fine research facilities. The goal of the research team is to clarify the hydrocarbon cycle in the context of cross-stratigraphic organic-inorganic interactions, expand the new theory of hydrocarbon generation under organic-inorganic interactions, and establish the enrichment mechanism of abiogenic gas and geothermal resource, and clarify the comprehensive resource effect of deep geological processes, so as to serve China's future " carbon neutrality & emission peak " strategic goal.
