To clarify how pressure and pore structure regulate CO2 spatial accessibility, residual oil mobilization, and morphology redistribution after waterflooding, three quasi-two-dimensional microfluidic pore networks were investigated at nominal outlet back pressures of 10, 15, and 20 MPa. The apparent minimum miscibility p...

Polymer-surfactant binary flooding, as a core technical system in chemical flooding, has achieved breakthrough application results in heterogeneous reservoir development through synergistic mechanisms of mobility control and interfacial tension reduction. However, the significant nonlinear correlation between technical...

Fractured shale oil reservoirs possess ultra-tight matrix pores and suffer unsatisfactory oil recovery under conventional exploitation, while systematic comparisons among CO2 flooding, CO2/CH4 mixed gas flooding, and multi-component thermal fluid (MTF) flooding remain insufficient for guiding field-parameter design. Th...
