Abstract：As one of the important seismic attributes,phase contains reflection structure information.Based on the assumption of the double-reflection coefficient combination and the seismic wavelet constant phase,we derive a new relationship between the phase spectrum and the stratum thickness.And we use this relationship to estimate thin bed thickness.Compared with conventional phase-to-thickness relationship,the new relationship avoids the singularity problem of phase tangent functions,reduces the instability caused by different frequency bands,and improve the feasibility of thin bed thickness estimation with phase spectrum.Real data applications show that thin bed thickness estimated by the proposed approach matches very well with that interpreted on logging data,which provides a good base for the latter exploration deployment.
