Abstract The most important problem in interpreting multi-wave seismic data is multi-wave calibration and contrast, in which the extraction of the reflection coefficient and the selection of the wavelet are most critical. However, Zoeppritz equation is extremely complex and does not have intuitive physical meaning, and hence it is difficult for this equation to receive a direct application. This paper therefore makes a detailed description of five approximate formulae, based on analyzing the suitability of six models with the variation of the angle of incidence. It is concluded that the approximate formula Aki&Richard generally has better adaptability.
