分频处理技术在辽河深层地震资料处理中的应用

Application of frequency divided processing technique in the processing seismic data from the deep-seated formations in Liaohe oil field.

长期以来 ,深层资料品质差 ,信噪比、分辨率低是石油勘探中带有普遍性的难题。人们从野外采集、资料处理等各个环节 ,一直在努力寻找解决这一难题的有效方法。通过大量的分析研究 ,我们认为分频处理是展宽频谱、提高信噪比和分辨率的理想方法 。

It is a difficult problem of universality in seismic exploration for a long time that the seismic data from deep seated formations are poor in quality and low in S/N ratio and resolution. People have made great efforts in all aspects of acquisition and data processing. After intensive analysis and research, we believed that frequency divided processing technique is an ideal method for frequency spectrum spread as well as S/N ratio and resolution improvement, Therefore it is an effective means to improve the quality for data from deep seated formations.
