摘要
本文给出了一种适合用测井曲线作模型,考虑吸收和频散的制作合成垂直地震剖面(SVSP)的快速算法,即先在频率域计算SVSP,再经傅氏变换回到时间域。这种算法具有以下特点:运算速度快,占用内存较少,能有效地压制离散傅氏变换的时域折叠效应。
In this paper, a fast algorithm for constructing the synthetic VSP was given. It takes the logging trace as the model, and in the process of computing, the absorption as well as the frequency dispersion are automatically taken into consideration. The usual way of doing the operation is to compute the VSP data in frequency domain, and then, to transfer the results into the time domain by Fourier transformation. The merits of such algorithm are: high operating efficiency, less internal storage and the depression of the folding effects arisen from the discrete Fourier fransformation.
