Gas breakthrough pressure is a key parameter to evaluate the sealing capacity of caprock,and it also plays important roles in safety and capacity of CO_(2)geological *** on the published experimental results,we present numerical simulations on CO_(2)breakthrough pressure in unsaturated low-permeability rock under 9 multiple P-T conditions(which can keep CO_(2)in gaseous,liquid and supercritical states)and thus,a numerical method which can be used to accurately predict CO_(2)breakthrough pressure on rock-core scale is *** simulation results show that CO_(2)breakthrough pressure and breakthrough time are exponential correlated with P-T ***,pressure has stronger effects on experimental results than that of ***,we performed sensitivity studies on the pore distribution indexλ(0.6,0.7,0.8,and 0.9)in van Genuchten-Muale *** show that with the increase ofλ,CO_(2)breakthrough pressure and breakthrough time both show decreasing *** other words,the larger the value ofλis,the better the permeability of the caprock is,and the worse the CO_(2)sealing capacity *** numerical method established in this study can provide an important reference for the prediction of gas breakthrough pressure on rock-core scale and for related numerical studies.
