The fatal challenge that human beings are currently facing is global warming as a result of excessive CO2 emission in the atmosphere. sequestration, gaseous injection into ultra-tight geological sites, regarded promising approach to achieve reduction substantially. In this work, emphasis paid storage potential inside depleted shale or coal seam where presence nanopores rich, and molecules store both bulk adsorption states nanopores. microscopic characterization on behavior nanospace, particularly quantitative description difference between states, still lacking. With intention shed light nanoconfined behavior, simple yet robust theoretical work rooting chemical equilibrium each molecule entire system implemented, shift critical properties due nanoconfinement effect coupled. Then, density can be described function distance away from nanopore wall; found accumulate more densely while approaching wall, suggesting an perspective. Results show (a) adsorption-phase thickness insensitive size, ranging 0.58 0.64 nm, ratio over could reach 1–2 orders magnitude; (b) amount 2 nm able 7.2 times macropores, displaying unique advantage formations sequestration conventional oil/gas reservoirs; (c) increasing pressure improve total performance, improvement magnitude at low-pressure range great 2.9 high-pressure range. This provides doable framework investigate existence nanopores, enriching basis identify favorable sites for sequestration.

Weakly volatile fracture-pore type carbonate reservoirs are characterized by the presence of fractures and complex pore structures, yet fluid distribution patterns across different types remain unclear. To address this, this study categorizes pores into fractures, large pores, small based on observations from cast thin sections. Significant differences in flow characteristics found among these fractures. Building upon parameter characterization methods established previous research, paper integrates improves approaches, developing a comprehensive calculation method for permeability, capillary pressure, relative permeability applicable to types. Based three-phase model fracture–large pore–small triple porosity system is developed, successfully simulating migration oil gas under various development methods. The results indicate that during depletion stage, remaining primarily resides pores; after water injection, recovery increases significantly. However, later stages exhibit an “oil-locking” phenomenon, while show “residual gas.” A comparison injection indicates asynchronous production can help maintain reservoir pressure stability reduce utilization This provides important theoretical foundation efficient weakly reservoirs.

The Early Carboniferous Dawuba Formation within the Yadu-Ziyun-Luodian aulacogen (YZLA), southern China, represents a significant shale gas play formed dynamic platform-basin transitional sedimentary system influenced by multi-sphere coupling (the interaction of tectonic, climatic, and oceanic spheres). This setting generated pronounced heterogeneities in lithology content. Integrating field geological surveys well data, this study comprehensively evaluates mineralogy, geochemistry, structural features, content these shales to decipher key factors controlling enrichment, particularly tectonically complex area. A crucial finding is distinction between low-energy, “thick-bedded” deposits higher-energy, “thin interbedded” sections characterized frequent alternations mudstone argillaceous limestone (0.5–5 m single layers, mudstone:limestone ratio 1:1–1:2). Significantly, thin interbedded demonstrate superior reservoir quality, exhibiting higher porosity (∼2.9%) notably (∼2.5 3 /t). We reveal that YZLA’s setting, primarily governed preservation conditions dictated unique litho-mechanical properties strata, rather than traditional like TOC abundance or matrix porosity. interlayering promotes stable micro-fractures, supported clay-rich horizons effectively sealed compact limestone, thereby enhancing secondary storage capacity permeability for free gas. Consequently, represent most favorable intervals accumulation, identifying them as prime targets achieving breakthroughs YZLA.
