Since the parameter distributions across the reservoir are not available with the existing probes, the stochastic finite element method is combined with a two-phase flow model to establish an unconditional random field of permeability, and computations are performed using the Monte Carlo method. The permeability, CO<sub>2</sub> maximum migration distance (<i>M<sub>d</sub></i>) and CO<sub>2</sub> sweep area (<i>S<sub>a</sub></i>) were analyzed for mutual correlation. The permeability correlation area affecting <i>M<sub>d</sub></i> and <i>S<sub>a</sub></i> was obtained, and the changes in the correlation area under the coefficient of variation (<i>C<sub>v</sub></i>) and correlation length (<i>λ<sub>x</sub></i>) of the permeability field in the different reservoirs were analyzed. The kriging superposition approach (KSA) was subsequently used to estimate both the <i>M<sub>d</sub></i> and <i>S<sub>a</sub></i> of the target reservoir by establishing conditional random fields based on the sampling parameters in regions with different correlations, resulting in errors of 0.66% for <i>M<sub>d</sub></i> and 0.96% for <i>S<sub>a</sub></i> in the high correlation region and 4.86% and 3.12% for <i>M<sub>d</sub></i> and <i>S<sub>a</sub></i> in the low correlation region, which suggested that the sampling results from the high correlation region were less biased in the estimation.

Geological storage of CO<sub>2</sub> provides a solution with the lowest economic cost and the fastest effect for reducing CO<sub>2</sub> emissions. This article proposes a CO<sub>2</sub> storage regional division method based on the characteristics of low-permeability reservoirs in the Yanchang W oilfield in China.

As the displacement progresses, the volume of the gas phase region and the two-phase or near-miscible region gradually increases; the volume of the diffusion region first increases and then decreases. By calculating the storage capacity of each region separately, the total storage capacity is finally calculated. The impact of different pressures and injection rates on dynamic CO<sub>2</sub> storage capacity was evaluated.
