摘要
文章对Canley计算井中震源SVSP的算法作了改进和推广,使之可以包含吸收和频散的影响,从而能有效地压制时域折速效应,并提高了用复杂介质模型制作SVSP的运算速度。改进后的SVSP算法是在频域内计算,然后变换到时域,它具有所占内存夕、运算速度快的特点。
An improvement on the Canley's algorithm for calculating synthetic vertical serismic profiles (SVSP) of buried source is made in this paper. By the improved algorithm, the effects of absorption and dispersion is considered, aliasing in time domain almost completely eliminated, and. thus the speed to calcule SVSP of complex models increased greately. The SVSP are calculated in frequency domain and Fourier transformed back into time domain. The algorithm is characteriZed by fast computation and less internal storge.
