Method of seismic signal processing and exploration

摘要

A method for the exploration of hydrocarbons, comprising the steps of: obtaining a set of seismic signal traces distributed over a pre-determined three-dimensional volume of the earth; dividing the three-dimensional volume into a plurality of vertically stacked and generally spaced apart horizontal slices; dividing each of the slices into a plurality of cells having portions of at least three seismic traces located therein; measuring the cross-correlation between one pair of traces lying in one vertical plane to obtain an in-line value and the cross-correlation between another pair of traces lying in another vertical plane to obtain a cross-line value; combining the in-line value and the cross-line value to obtain one coherency value for each of the cells; and displaying the coherency values.
