Effectiveness evaluation and field application of CO2-viscoelastic fluid synergistic flooding in low-permeability tight reservoirs
CO2 sweep efficiency and gas channeling are key factors restricting the effectiveness of CO2 flooding in low-permeability tight reservoirs. To address the technical issues of low sweep efficiency and gas susceptibility to channeling in CO2 flooding, a viscoelastic fluid system (CMS) was proposed to...
