三维声学模型实验 (3—D acoustic model experiments),P.Newman (G—56) 对按比例的声学模型研究的结果,能为许多三维地震成象问题提供有价值的认识,也将对实地三维地震勘探选择合适的记录参数起到重要的作用。用休斯顿大学地震声学实验室里取得的Salcol—2模型数据完成了这些实验,模型模拟了埋入在不同性质的均匀地层里的弯曲河床。倘若在时间和空间上有足够的采样数据,那么用克希霍夫二步求和法做的三维偏 3-D acoustic model experiments, P. Newman (G-56) The results of a scaled acoustic model study can provide valuable insights into many 3D seismic imaging issues, as well as a three-dimensional Seismic exploration to choose the appropriate recording parameters play an important role. These experiments were done with the Salcol-2 model data obtained at the Seismological Acoustics Laboratory at the University of Houston, which model a curved riverbed buried in a homogeneous formation of varying nature. If there is enough time and space sampling data, then using Kirchhoff two-step summation method to do the three-dimensional
