【摘要】 针对具有垂直对称轴的横向各向同性(VTI)介质,研究了多波速度与地层各向异性系数之间的关系。采用适应大偏移距以及强各向异性介质的双平方根方程,进行速度和各向异性系数分析,并将批量计算与交互解释相结合,实现了高精度各向异性介质多波速度与各向异性系数提取,并形成了一套利用多波地震资料求取地震波纵、横波速度及各向异性系数的方法和软件。所求取的参数可用于多波地震资料处理,提高多波资料的成像质量,也可为地层地质解释提供参考。实际资料的应用效果证明了该方法和软件的正确性及有效性。更多还原

【Abstract】 Based on the characteristics of vertical transverse isotropic(VTI ) media, the relation between multi-wave velocity and anisotropic coefficients have been studied, and multi-wave velocity and anisotropic coefficients analysis is realized by using the double square root equation, which adapts to long offset and strong anisotropy. By combining batch computing with interactive interpret, the high precision multi-wave velocity in anisotropic media and anisotropic coefficients are obtained. The method and software have been developed to analyze the P-P and P-SV wave velocity and anisotropic coefficients. These parameters can be applied to multi-wave data processing to improve the image quality and serve the geology interpretation. The real data processing verifies the correctness and validity of the method and software.更多还原
