| 英文摘要 | In this paper the synthetic seismograms of P-and PS-wave reflections from the top and bottom of a thin layer are calculated in case of isotropic media. The results show that both P-and PS-wave reflections are composite waves resulted from different types of conversion as transmitted and reflected on two interfaces of the thin layer, and have the pulse wave form similar to reflections from single interface. The amplitudes of two kinds of reflections decrease as layer getting thinner, but are on the same level as that of single interface reflection, even if the thin layer decreases to 2 m thick when the dominant frequency is 40 Hz. The reflections from extremely thin layer below 1 m thickness are weak and even disappear. There is a relationship between composite amplitudes of thin layer reflections and offset, however, which is not unique. The theory and method for single interface reflection, about the amplitude versus offset (AVO) is not suitable to interpret and invert for thin layer parameters. |
