Depth domain seismic attribute extraction method based on displacement field

The invention provides a deep domain seismic attribute extraction method based on a displacement field. The method comprises steps: 1, geological horizon interpretation and fault interpretation are carried out on the deep domain seismic data; 2, in the deep domain, the displacement field information of a geological body is analyzed; 3, deep domain seismic attribute extraction based on the displacement field is carried out; and 4, through the deep domain seismic attribute result, the distribution law of the geological body is analyzed. According to the deep domain seismic attribute extraction method based on the displacement field, a deep displacement field containing the geological body information and corresponding to the interpretation horizon is provided, the deep displacement field serves as a basis for time window definition in the case of attribute extraction, the distribution features of the geological body are obtained as the attributes are extracted through the displacement field, and the result is m
