【摘要】 在时间-空间域的地震记录中,薄层和薄互层的识别是件很困难的事情,它受到常规地震记录有限的分辨率和较低信噪比的严重限制。用小波变换对地震记录做分频频移处理,即把地震记录转换到小波分频域中,则薄层的识别变得相对简单,薄层和薄互层的厚度反演也成为可能。本文提供的合成地震记录和实际地震记录计算的实例说明了所提方法的精度与可行性。更多还原

【Abstract】 In conventional time-space domain the identification of thin layer and thin interbed layer on seismic record is quite difficult due to the very limited resolution and lower signal to noise ratio of the seismic data. By wavelet transform of the seismic data we can get a set of frequency division profile(FDP) in which the identification of a thin Layer becomes relatively simple and the thickness inversion of thin layer or thin interbed layer is also possible. The inversion results of some synthetic seismic data and seismic real data show that the algorithm presented in this paper is effective and accurate.更多还原
