The effects of shale pore structure and mineral components on shale oil accumulation in the Zhanhua Sag, Jiyang Depression, Bohai Bay Basin, China

The pore structure and mineral components of shale have different effects on the enrichment of different phases of shale oil. Thus, research on the relationships between shale's pore structure and mineral components and shale oil enrichment is particularly important. Using core observations, scanning electron microscopy, whole rock mineral diffraction analysis, CO2 and N2 low-temperature and -pressure adsorption experiments and nuclear magnetic...
