Zusammenfassung: | The invention discloses a trace operation azimuth amplitude ellipse fitting crack detection method, belongs to the technical field of oil-gas exploration, and solves the technical problems of large calculation amount, low operation efficiency and the like of an existing pre-stack azimuth seismic crack prediction method. The invention discloses a channel operation azimuth amplitude ellipse fitting crack detection method, which comprises the following steps of: on the basis of an HTI medium theory, by taking azimuth amplitude ellipse fitting crack detection as a principle, deducing an ellipse formula again, establishing a channel-based ellipse fitting solution equation, and quickly solving by using a singular value decomposition (SVD) algorithm. High-precision fracture development intensity and azimuth data are efficiently obtained, and the problems that a conventional pre-stack seismic fracture prediction method is large in calculation amount and low in operation efficiency are solved; the operation speed of t |
