METHOD AND APPARATUS FOR THE ANALYSIS OF SEISMIC RECORDS

摘要

A method of analyzing a recorded seismic signal. An input signal impressed on the earth is controlled by a known drive signal. A Wiener operator W is derived from (a) this known drive signal and (b) a selected desired output signal. Reflections from the transmitted input signal are recorded. The received or recorded signal is convolved with the Wiener operator W to obtain the convolution thereof. The convolution contains compressed signals to indicate reflections from subsurface interfaces. Any known input signal and any selected output signal can be used.
