The invention relates to a rapid three-dimensional horizon interpretation method based on horizontal navigation. The rapid three-dimensional horizon interpretation method based on horizontal navigation includes the following steps that (1), seismic data for horizon interpretation are processed in an interpretative mode, and a seismic data volume highlighting horizon information is obtained; (2), time slices near horizons are extracted, a fault interpretation result is projected to the time slices, and the time slices serve as horizontal navigation slices for horizon interpretation; (3), a horizon interpretation scheme is built; (4), another seismic section which can enter the next fault block without passing through faults is selected according to the horizon interpretation scheme, and horizon interpretation of the seismic section is carried out on the seismic data volume so that the horizon interpretation scheme can be introduced to the next fault block; (5), horizon interpretation of all the seismic sections of the faults within the whole area is finished; (6), the point of intersection between the horizon interpretation and fault interpretation is calculated and projected to a seismic work area base map, plane polygons of the faults on the horizon are compiled one by one, meshing calculation of the interpretation result of the horizons is carried out under the constraint of the plane polygons of the faults, the structural meshed plane of the horizons is obtained, and horizon interpretation is completed; (7), the steps (3)-(6) are carried out repeatedly, and interpretation of the horizons of the whole area is finished.
