Simulation Study of Influence of Nano-Confinement Effect on Shale Fluid Phase Characteristics: A Case Study of Gulong Shale Oil

Processes
Songliao Basin hosts abundant shale oil and gas resources, yet the phase behavior of the fluids is still unclear since the confinement effect of the shale reservoir alters the adsorption effect on the pore walls. In this study, molecular dynamics (MD) simulations were employed to clarify this issue.
