Waterflooding in tight reservoirs is a key focus the recent oilfield development, making it essential to accurately assess injection rate effect sandstone. This study investigates relationship between and residual liquid film (water oil film) thickness, as well underlying mechanisms, by conducting oil-driven water experiments combined with molecular dynamics simulations. The morphology of formed under different rates serves primary this research. experimental results indicate that increases, volume stagnant bound gradually decreases stabilizes. Molecular simulations reveal displacement process can be categorized into three stages: rapid stage, slow smooth stage. In system, thickness final more uniform. As recovery decreases. However, once reaches certain threshold, decline slows down. provides theoretical foundation reference data for selecting optimal waterflooding operations reservoirs, contributing improved velocity.
