地震波形分类技术在黄骅坳陷孔三段沉积体系分析中的应用

摘要

The distrihution of the depositional systems in the 3rd member of the Kongdian Formation in the Huanghua depression is dealt with in the light of 3D seismic waveform classification techniques. Four seismic waveform facies profiles are constructed by using the stratimagic software, and show a general agreement with the distribution map of the depositional systems obtained by geological methods.%在Stratimagic软件环境下,通过对黄骅坳陷孔南地区三维地震数据逐道对比分类,细致地刻画地震信号的横向变化,从而得到与4个层序对应的波形分类相图,结合地质资料,最终得到波形分类相图解释图,其与通过地质方法得出的沉积体系展布图的展布规律大体一致.
