METHOD FOR GEOLOGICALLY MODELING SEISMIC DATA BY TRACE CORRELATION

摘要

The present invention relates to a method for developing a geological model from previously collected seismic data, characterized in that the method includes the steps of: sampling said seismic data according to at least one set of traces (3, 4) of a predetermined gradient, each of which consist of sampling points; analyzing similarities between the seismic data around said sampling points (5); determining connections (7) between sampling points that belong to different traces on the basis of said analysis; forming a geological model that attributes, to each sampling point, a relative geological age that is calculated at least on the basis of connections related to said sampling points and the relative geological age of other sampling points in the vicinity of the trace that includes said sampling point.
