Abstract

The invention relates to a coated anticline boundary identification method, and belongs to the technical field of oil and gas field exploration and development. The method comprises the following steps: firstly, acquiring seismic data, carrying out spectral analysis on the seismic data, rotating the phase of the seismic data, carrying out relative isochronous surface horizon interpretation on the rotated data, leveling an interpreted seismic top surface layer, determining a stratigraphic slice on the leveled seismic data, and according to the amplitude attribute and the transverse difference of the stratigraphic slice, determining the seismic data according to the stratigraphic slice. And an anticline plane form is identified. According to the method, the earthquake high-resolution processing cost is saved, and the problem that the imaging effect uncertainty is increased due to high resolution is solved.
