The invention discloses a foam performance measurement device of a foaming agent system for chemical flooding and a using method of the device, and also discloses a device for performing quantitative evaluation on foam performance of the foaming agent system for chemical flooding, a method for evaluating attenuation of the foaming volume of the foaming agent system, and a method for evaluating the foam liquid carrying stability of the foaming agent system. Data obtained by the foam performance measurement device is used by all the methods, and evaluation is further carried out. The evaluation methods are used for analyzing and screening the foam performance of the foaming agent system, and the foam performance is comprehensively evaluated in a quantitative way; the methods are simple, objective and accurate, and are good in repeatability, small in error and good in operability and practicality, and a scientific theory basis is provided for determination of the foaming agent system. Related calculating parameters in the evaluation methods can be adjusted and changed according to practical application situations, so that the evaluation methods are suitable for foaming agent systems in more fields.
