The invention provides a heterogeneous flooding remaining oil simulation method based on multi-data comprehensive application, and the method comprises the steps: 1, carrying out the correction of a geologic model based on logging and dynamic monitoring data; 2, parameters of the heterogeneous displacement process are set, and the change rule of PPG particles in the heterogeneous displacement process is simulated; 3, chemical agent parameters are adjusted for heterogeneous flooding history fitting; 4, detecting the fitting precision of the model by comprehensively utilizing various data; and 5, carrying out heterogeneous flooding remaining oil distribution rule research, and analyzing plane, interlayer and intra-layer remaining oil change rules after heterogeneous flooding. According to the heterogeneous flooding remaining oil simulation method based on multi-data comprehensive application, the research accuracy of heterogeneous flooding remaining oil is greatly improved, and the method has very good guiding
