METHOD FOR LOCATING IMPEDANCE DISCOUNTINUITIES IN A WAVE PROPAGATING MEDIUM

摘要

A method for digitally processing seismic data, or other similar data derived for propagating wave energy to produce a data image comprised of a plurality of coordinate points is described. Each coordinate point has a value which is a combination of the amplitude values taken from a plurality of primary seismic traces at the travel times on the respective primary traces required for energy to travel from the respective source points to the coordinate point and return to the respective receiving points of the seismic traces. More particularly, the combination is accomplished in such a way as to increase the signal-to-noise ratio by selected data to be combined at the respective coordinate points either on a predetermined basis or automatically by an analysis of the data.
