通过对南阳凹陷张店油田高分辨率三维地震资料解释,总结出了适合高分辨率地震资料解释的分步法解释技术,即首先在低频地震数据体上进行宏观的构造解释,在此基础上,在中高频地震数据体上进行岩性解释。

The technique of fractional step interpretation isproposed in accordance with high resolution 3-D seismic data interpretation work conducted in the Zhangdian Oilfield, Nanyang Depression. In the technique, macroscopic structures are interpreted first for low frequency seismic data volume. On the basis of this, lithologic interpretation is then performed for middle and high frequency data volume.
