There is increasingly valued attention on whether the matter and energy carried in deep fluids can significantly change hydrocarbon (HC) generation of low-mature source rocks. Previous studies suggest that upward movement to sedimentary basins will HC evolution mode rocks, by fluid transform process as transient events. However, there a lack quantitative evaluation specific changes gaseous modi...

The molecular models of nanopores for major rock constituents in deep shale were constructed. microscopic adsorption behavior methane was simulated by coupling the grand canonical Monte Carlo and Molecular Dynamics methods effect discussed. Based on illite kerogen nanopore models, discrepancies water distribution characteristics elucidated, effects its underlying mechanisms revealed, competitiv...

The continental lake basin is a favorable accumulation area of shale oil and gas; however, the organic matter enrichment regularity in facies still controversial, which hinders exploration gas Sichuan Basin. In this study, relationship between sedimentary environment was analyzed by petrology inorganic geochemistry tests 153 samples. results show that different lithologic associations Da’anzhai...
