PROBLEM TO BE SOLVED: To provide a method and an apparatus for measuring residual carbon dioxide in a pore for geological sequestration of carbon dioxide.SOLUTION: The method for measuring residual carbon dioxide in a pore for geological sequestration of carbon dioxide includes: a first step (S102) of calculating a first thermal conductivity of a storage layer by measuring temperature variation by depth of the storage layer; a second step (S103) of filling carbon dioxide into a pore formed in the storage layer by injecting a predetermined amount of carbon dioxide into the storage layer; a third step (S104) of calculating a second thermal conductivity by measuring temperature variation by depth of the storage layer while keeping the carbon dioxide filled into the storage layer; a fourth step (S105) of capturing carbon dioxide in the storage layer by injecting water in the pore of the storage layer while keeping the carbon dioxide filled into the storage layer; a fifth step (S106) of calculating a third thermal conductivity of the storage layer while keeping the carbon dioxide captured in the storage layer; and a sixth step (S107) of calculating a saturation rate of residual carbon dioxide to be captured in the storage layer by water to be injected based on the first to third thermal conductivity.
