Damage Mechanism of Oil-Based Drilling Fluid Flow in Seepage Channels for Fractured Tight Sandstone Gas Reservoirs

Figure 6

Distribution of oil-gas-water after OBDF invasion (the dotted lines are fracture walls from different zones, and the text indicates the liquid mixing state in different zones; this zoning is an idealized figure for more clearly described multiphase fluids, and the actual fluids are more complex).
