本文研究了横波地震勘探物理特征与方法方面的已知程度,对激发横波的震源作了系统分析,其中以y方向力类型的脉冲线性定向震源的研究最为成熟,并在技术上可行。高度评价了采用多次复盖观测系统并按共深度点追踪PS型转换反射波的前景。研究了基于综合应用纵波、横波及转换波的多波地震勘探的方法问题,并提供了试验实例。这种做法在仔细部署并得到验证后就可建议更广泛地将它用于解决构造问题,而且主要是解决预测地质剖面的非构造问题。
In this paper, we study the known degree of physical characteristics and methods of shear wave seismic exploration, and systematically analyze the source of shear wave excitation. Among them, the study of y-directional pulsed linear directional source is the most mature and technically feasible. Highly evaluated the prospect of using multiple cover observation systems to track PS-type reflected reflections at a common depth. The method of multi-wave seismic exploration based on the comprehensive application of P-wave, S-wave and converted wave was studied and the experimental examples were provided. After careful deployment and verification, this approach suggests that it be used more broadly to solve structural problems and that it is mainly to address non-structural problems in predicting geological sections.
