CALCULATION OF REFLECTION COEFFICIENT IN FREQUENCY-WAVE-NUMBER DOMAIN USING SEA- FLOOR SEISMIC MULTI-COMPONENT DATA

An algorithm for decomposition of multi wave and multi component data into upgoing and downgoing P wave and S wave was derived in frequency wave number domain in this paper. The reflection coefficient versus incident angle (RVA) was calculated, which can provide foundational data for the AVO inversion of elastic parameters and prediction of fluid factor. The results of the synthetic multi component data show that the information of reliable RVA can be extracted from multi waves and multi component seismic at the sea floor by the method given in this paper.
