摘　　要：近年来，小波变换作为一项新理论在三维地震数据的处理中日益受到重视。本文利用小波变换的变焦特性及思想设计了一缩短地震子波长度、提高地震子波主瓣与旁瓣幅度比的算法，并将此算法运用于胜利油田孤岛东斜坡Ｂ７０１井三维地震数据处理中。In recent years waveletf transformation as a new theory has been attnracted the atten tion in 3 D seismic data processing day by day. By using the change focus characteristics of wavelet and its idea an algorithm for reducing the length of seismic wavelet and raising the amplitude ratio main part to side part in seismic wavelet has been designed in this paper. This algorithm has been used in 3 D seismic data processing in Gudao Dongxiepuro, B701 borehole, The results express that this algorithm is very efficient in raising the thickness resolution of earth layers.
