Abstract:The stress and adsorption motivation deformation during
shale oil
production directly affect its development dynamics. First, a mathematical
simulation of pore deformation in shale oil under stress motivation
is established. We analyzed the impact of factors including the reservoir
pressure, Biot coefficient, bulk modulus, and tortuosity on the deformation
characteristics of nanopores. Second, a pore deformation model under
multifactor synergistic effect is derived by combining the molecular
dynamics, which ta… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
