Mechanism Identification and Differentiated Control of CO2 Gas Channeling in the Chang 6 Low-Permeability Reservoir of the Qiaojiawa Oilfield
CO2 channeling limits the effectiveness of immiscible flooding in the Chang 6 low-permeability reservoir of the Qiaojiawa Oilfield. This study integrates core- and fluid-property data, slim-tube minimum miscibility pressure (MMP) measurements, facies-controlled geological modeling, and CMG-GEM compositional simulation...
