本文遵循模型与地质构造相似原理的基本准则,以模型地震学为基础模拟假想的地质构造,采用偏移垂直剖面法和反向反射法进行测试,并根据测试记录分析了二维层状模型及断层构造模型中弹性波垂直时间场的某些特点,以为垂直地震剖面法的地质解释奠定基础。

Following the basic criteria, the model is analogous to the geological structure, and based on the model seismology to simulate the supposed geological structure and to make measurement using the migrating vertical seismic profiling and reversal reflection technique. In the light of record measured, some characteristics of the vertical time field of elastic wave in 2D stratified model as well as the fault structural one are examined so as to lay a foundation for geological interpretation of vertical seismic profiling.
