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。结果表明此算法对提高地层厚度分辨率是卓有成效的
In recent years, wavelet transform has been paid more and more attention as a new theory in the processing of 3D seismic data. In this paper, an algorithm to shorten the length of seismic wavelet and improve the ratio between the mainlobe and the sidelobe of the seismic wavelet is designed based on the zoom characteristics and the idea of wavelet transform. The algorithm is applied to 3D seismic data processing of B701 well in the east slope of Gudao Oilfield . The results show that this algorithm is effective in improving the resolution of formation thickness
