摘要
本文讨论用渐近射线理论制作VSP非零偏移距任意形状界面模型的原理和方法, 给出了用本方法对倾斜层、断层、尖灭、弯曲界面、透镜体等几类常见模型制作的实例, 并描述了各个模型上VSP响应的特征, 了解这些特征有助于VSP的野外施工设计和VSP资料的解释。
Abstract
In this paper, the principle and technique of modelling the non-zero offset VSP with arbitrary boundries by asymptotical ray-tracing was examined. Examples with relation to the modelling of tilted strata, the faults, the thinning outs, the curved subsurfaces, lenses, etc., were presented and the VSP responses to each model were described.
