摘要
本文利用有偏垂直地震剖面P波、SH波走时曲线, 研究层状横向各向同性介质参数的反演方法。对于SH波走时曲线, 用双曲线拟合法确定两个弹性参数;对于P波走时曲线, 则利用双曲线拟合和遗传算法相结合的方法反演其余三个弹性参数。
Abstract
This paper studies the method to inversc the parameters of laycred transverscly isotropicmedia using P, SH-waves traveltime curves of offset vertical scismic profilc. For SH-wavetraveltime curves,hypcrbolic fitting is used to estimate two elastic parameters; while for P-wave,both hyperbolic fitting and genetic algorithm are combined to determine the other three elasticparameters.
