The present invention relates to a seismic facies control-based sedimentary microfacies recognition method. The method includes the following steps that: 1) logging information is normalized; 2) fine horizon calibration is performed; 3) a model framework is determined; 4) a low frequency model is established; 5) a seismic data impedance value and a formation reflection coefficient are obtained, if synthetic trace data are in optimal matching with an actual seismic data trace, and drilling impedance is in optimal matching with seismic data impedance, and the method shifts to step 6), otherwise, the method shifts to the step 3); 6) well seismic constraint inversion is performed, a wave impedance inversion data body is obtained; 7) the top and bottom of a reservoir are traced and explained, with the top reflection layer and bottom reflection layer of the reservoir adopted as control surfaces, interlayer attributes are extracted from the inversion data body; and 8) seismic attributes are utilized to constrain the boundaries of sedimentary microfacies, and the spread of the sedimentary microfacies is described. According to the method, the logging information is adopted to constrain seismic inversion, and therefore, the resolution of an inversion result can be improved, the sedimentary microfacies of a target interval can be well depicted, the planar distribution of a thin sand layer can be predicted, and a basis can be provided for well location deployment.
