摘要

在薄互层地震资料分析中,以三参数小波为分析小波,针对薄互层地震信号的特点,恰当地选取三参数小波中的参数,使其不仅适合于分析包含慢变频率和振幅分量的信号,而且也适合于包含快变分量的信号;该方法既能刻画薄互层的沉积旋回,同时也能用于研究薄互层内部的局部结构。通过模型和实际资料算例验证了其有效性,在进一步完善后有望成为岩性勘探中的有效方法。
In seismic data analysis of thin interbeds, we use TP wavelet as analyzing wavelet with appropriately choosing parameters of TP wavelet according to properties of seismic signals of thin interbeds and let it be suitable for analyzing signals containing not only slowly varying frequency and amplitude components, but also rapidly varying ones. This method can characterize the deposit gyration of thin interbeds and explore local structure of thin interbeds. Its effectiveness is proved by model and field data and hopefully becomes a powerful method in exploration of rock properties after further development.
