Description
technical field [0001] The present invention relates to CO 2 The technical field of geological storage research, in particular to a reservoir geological storage body CO 2 A device and method for analyzing the impact of escape on the environment. Background technique [0002] CO 2 When injected into the reservoir storage body, there are generally two escape behaviors, diffusion escape and seepage escape; the first diffusion escape behavior is due to the CO2 inside the reservoir storage body. 2 The concentration is higher than outside the storage body, CO 2 Molecules will escape to the outside of the storage body in the form of diffusion, and the CO 2 The storage effect is destroyed; the second type of seepage escape behavior is when the pressure of the storage horizon exceeds the breakthrough pressure of the caprock, CO 2 It will escape to the outside of the reservoir by the seepage of the continuous phase, resulting in a large-scale escape behavior, which is harmful to ...
