Device and method for displaying full azimuth angle domain image data

摘要

A device, system, and method for displaying seismic image data may include computing, from a wide-azimuth data set, a discrete data set associated with an image function at a seismic image point. The discrete data set may be mapped onto a continuous curved three-dimensional surface. The mapped data set may be projected onto a continuous planar surface. The projected data may be displayed as a planar disk. A plurality of continuous planar surfaces, each representing a single image point, may be assembled to form a three-dimensional body, representing a seismic gather of image points. The three-dimensional body may be displayed. Other embodiments are described and claimed.

1. A method of generating a computational mesh that approximates a sphere for displaying seismic image data, the method comprising:
generating a polyhedron with flat faces inscribed in a sphere; replacing one or more of the flat faces of the polyhedron with curved faces that have edges approximating the arcs of the sphere; splitting one or more of the curved faces to increase the number of faces of the polyhedron; repeating said splitting step a plurality of times to generate a final polyhedron that approximates the sphere; generating a computational mesh having nodes at vertices of the faces of the final polyhedron; and displaying seismic image data on the computational mesh to image subsurface geological structures.
