Summary Long-term high-flux waterflooding is a crucial technology for achieving the economic, environmental, and sustainable development of mature oilfields during ultrahigh water cut period by further reducing microremaining oil saturation (Sor) in swept area. However, traditional quasi-static two-phase flow simulations based on pore network models (PNMs) do not account impact cumulative volumes (PVs) through pore-scale remaining saturation, resulting inability to obtain distribution...
