hti构造煤方位avo正演
Keywords: hti介质,反射系数,对称轴夹角,裂隙走向
Abstract:
？以hti介质为例,在已知入射波射线参数条件下,精确求解了透射波速度和角度,在此基础上,推导出方位avo响应的精确表达式,并通过分析两种模型的avo散射系数曲线,得到以下认识:1对于上层为均匀各向同性介质,下层为hti介质的模型1,纵波反射系数最大值出现在90°方位,在靠近90°方位上波动小,在靠近0°和180°方位上波动大;快横波反射系数经过裂隙面和对称轴面发生极性反转,且峰值未出现在裂隙面和对称轴面,慢横波反射系数变化规律与之相反.2对于上、下层均为hti介质,且对称轴夹角取不同值的模型2,方位角相差180°的纵波反射系数曲线重合;当上、下层介质对称轴夹角为0°和90°时,纵波反射曲线关于裂隙面和对称轴面重合;快横波反射曲线在对称轴面发生连续性反转,在裂隙面发生间断性反转,慢横波反射曲线的变化规律恰恰相反.3在裂隙面和对称轴面上,快、慢横波只出现一种.通过对比快、慢横波反射系数经过裂隙面和对称轴面极性反转的特点,可以准确地确定裂隙走向.
