THREE-DIMENSIONAL ITERATIVE STRUCTURAL MODELING OF SEISMIC DATA

摘要

A process of three-dimensional iterative modeling where input data in the form of such as seismic time sections, related interval velocity information and seismic line location data are used to generate a three-dimensional depth-velocity model whose computed time response is compatible with the seismic data. The process functions to compare synthetic time sections with original data and then iteratively changing the model until the synthetic data is sufficiently close to the real data. Layers in the depth model are defined by gridded depth maps, velocity information is specified for each layer, and the time response of the model is computed by raytracing.
