Abstract

Energy geosciences and engineering fields in the context of carbon neutrality include geological storage of carbon dioxide and green hydrogen, enhanced geothermal energy utilization, efficient shale oil and gas extraction, as well as high-level nuclear waste geological repository. It involves sandstone, carbonate rock, mudstone, salt rock, granite, basalt and other rocks, along with natural and/or stimulated fractures. Such a geological system involves a wide nm-μm scale pore-fracture sizes, various pore connectivity and wettability, in addition to the coupled thermal-hydraulic-mechanical-chemical-biological (THMCB) process of deep earth environments. This presentation focuses on the matrix-fracture interaction, and establishes an independently developed complementary multi-method and multi-scale fusion (such as liquid-gas diffusion, hydrophilic-oleophilic phase nano-tracers, and micron-scale laser ablation-ICP-MS tracer element distribution imaging, etc.) for an integrated nano-petrophysics research system. It also demonstrates the unique application of large scientific equipment (small-angle neutron and X-ray scattering), and conducts innovations in theory (dual-zone pore connectivity) and methods (instrument development and application) to clarify whether the application of the above-mentioned rock masses in the field of energy geosciences and engineering can achieve the expected goals of cost-effective extraction and storage of various energy-related fluids, for realization of the carbon neutrality.
