地震相分析在深反射地震勘探资料解释中的应用

作者对INDEPTH项目深反射地震剖面的细致研究发现，在深反射地震剖面上不仅仅强反射同相轴可以反映地壳深部的结构、构造特征，而且其上的地震相特征在上、中、下地壳也有一定的差异。通过将地震相分析引入深反射地震勘探的研究中，可以利用地震相特征的差异对深反射地震剖面进行充分解释，为深部工作中的地壳结构、构造特征研究提供更丰富、可靠的资料基础。

APPLICATION OF SEISMIC PHASE ANALYSIS IN THE INTERPRETATION OF DEEP SEISMIC REFLECTION DATA

By a meticulous study of INDEPTH deep seismic reflection profiles,the authors found that not only the strong reflection line-ups of the deep seismic reflection profiles may reflect the structure of the deep interior of the crust but also the seismic phases in the upper,middle and lower crust have somewhat different features.By applying the seismic phase analysis in the study of deep seismic reflection exploration,we may use the difference in seismic phase features to interpret the deep reflection seismic profiles sufficiently,and thus more abundant and reliable materials may be provided for the study of the crustal structure.
