Method for judging movement direction of stratigraphic structure based on direction characteristics of rock core crack roughness

The invention provides a method for judging a stratigraphic structure movement direction based on direction characteristics of rock core crack roughness, and belongs to the field of geological exploration. The problems that when an existing method judges the movement direction of the stratigraphic structure, the accuracy is low, and the movement directions of multiple constructions are difficult to distinguish are solved. Spatial azimuth information of all cracks on a rock core within a certain depth range is obtained through a micro-resistivity scanning imaging logging technology and a drilled rock core, the cracks are grouped according to the spatial azimuth information, and on the basis, the shear slip direction of the cracks is judged by analyzing the surface roughness of crack surfaces in different directions, so that the shear slip direction of the cracks is judged. Performing statistical analysis on the shear slip direction of the same group of cracks to obtain the direction of a certain tectonic motio
