地震理论模型的计算

THEORETICAL CALCULATIONS FOR SEISMIC MODEL

在深部地质条件复杂的情况下,时间剖面上呈现出各种异常的和虚假的地震现象.这往往使我们难以直接从剖面上识别地质构造,甚至从而导出错误的结论.本文计算并分析了一些复杂的地质模型,直接为地质解释提供根据.这将有助于正确地判断时间剖面,力求合理地作出地震剖面的地质解释.

Various unusual and false seismic phenomena appear on the time sections obtained in areas where geologic conditions at depth are complicated. They often puzzle us and made it very difficult to identify the geologic structure directly from the sections, thus leading to fallacious conclusions.In this paper, the direct problems of computation for some complicated geologic models are made and analyzed, thus providing more basis for geologic interpretation. It might be helpful to interpret better the time sections, making proper geologic interpretation of seismic sections possible.
