The conventional reflection data processing is based on the assumption that the mediuin isisotropic. The anisotropy may affect the result of processing and interpretation such as velocityanalysis,time-to-depth conversion,migration and so on. So it is very important to understand thereflection time-distance curves. The paper deals with the traveltime curve calculation in transverse-ly isotropic media,gives the exact reflection time-distance curve equation. The corresponding traveltime approximation formula has been derived,which can be used in the traveltime calculation forsmall offset. In the case of large offset,for the quasi-P-wave an analytic formula can be used forthe calculation,and for the quasi-SV-wave a polynomial fitting method can be used for the process-ing. The traveltime curves obtained by numerical calculation show the effectiveness of the method.The formula in the paper can be applied to the fast calculation of the traveltime in transverselyisotropic media,and is also useful in the elastic parameter inversion and migration.

常规的反射数据处理都假定介质为各向同性。现已发现,各向异性会影响处理和解释的效果,如速度分析、时深转换、偏移等。因此,对于许多处理和解释,了解反射波时距曲线极为重要。本文研究了横向各向同性介质中的走时曲线计算,给出了精确的时距曲线方程,推导了相应的走时近似公式,它可用于小炮检距的走时计算。在大炮检距情况下,对于准P波,可用一解析校正计算;对于准SV波,则可用多项式拟合法来处理、数值计算所得的走时曲线表明了方法的有效性、文中公式可用于横向各向同性介质中走时的快速计算,对弹性参数反演和偏移等也很有意义。

WT5BZ]The aim of seismic data inversion is to assess the physical parameters (including density, elastic parameters and viscous elastic parameters). Defining the best assessing value to be a kind of parameters set, it is simulated that the synthesized seismic records are the most fit to those which were recorded in fields. A new way of directly elastic parameters inversion has be brought forward in the context. It is suitable to the inversion of elastic parameters in anisotropic media (HTI). It is totally different from those depicted in above content. In order to classify the strata properties, it utilizes both PP wave and PSV wave to inverse the strata elastic parameters ( C 11 and C 33 ). It could be called as the inversion of elastic wave equation.

Three - term Taylor series for t2 - x2 curves of P - P and P - SV waves over layered vertically transverse isotropic media are related to dimensionless parameters and vertical velocities of P - and S - wave, which provide a basis for seismic elastic parameter inversion. Only in middle spread, three- term Taylor series...

在VTI介质中,用非双曲线可以很好地近似P—P波中长排列情况下的旅行时;而对于P-SV波来说,应用非双曲线却不能很好地近似P-SV波的旅行时。对P-P波、P-SV波的旅行时进行三项泰勒展开时,它们的系数却包含了地震波的各向异性信息及其垂直速度信息,这为地震波的弹性参数反演提供了基础。实验分析表明,在中等排列长度下可以精确地得到P—P波、P—SV波旅行时的三项泰勒展式系数,从而可以精确地进行地层弹性参数反演。
