A corrosion inhibitor composition contains an organic long-chain compound having a polar group and hydrophobic silica. In a method for charging a corrosion inhibitor composition, the corrosion inhibitor composition constituted of a first corrosion inhibitor composition containing an organic long-chain compound having a polar group and a second corrosion inhibitor composition containing hydrophobic silica is charged into a fluid mixture including at least one hydrocarbon fluid selected from the group consisting of a liquid-phase hydrocarbon fluid and a gas-phase hydrocarbon fluid and water.
