Abstract
An imidazoline compound, a mobility control system, a plugging agent for gas channeling, and a method for carbon dioxide flooding. The structure of the imidazoline compound is represented by formula (1), in which R is pentadecyl, heptadecenyl, or heptadecyl. A mobility control system that contains the imidazoline compound can interact with carbon dioxide to form a plugging agent for gas channeling, and thereby attains a plugging effect for carbon dioxide channeling in a carbon dioxide flooding process.
