摘要：In this paper, we first recapitulate some basic notions of the CO2 sequestration and numerical model. Next, a mixed model is employed into the CO2 sequestration framework, for simulating CO2 geological sequestration processes. The last part of the paper makes extensions to evaluation of the effectiveness of CO2 sequestration with respect to atmospheric pressure, formation temperature, the initial reactant concentration, fracture aperture, and fracture dip. The results show that reactive Portland cement has a great impact on the effectiveness of CO2 sequestration, while the proposed mixed model is robust in simulation. © 2020 by the authors.
