I sketch out the following points. (1)·My unified formulas for reflection and transmission of plane elastic wave. ·Dynamic difference between converted wave and unconverted wave. ·The reflection and transmission coefficients of plane elastic and converted waves incident upon an interface between different elastic media are the odd functions of ray parameter p respectively. ·The reflection and transmission coefficients of unconverted wave are the even function of ray parameter p. (2)·Some power series type formulas for reflection and transmission of plane elastic wave, which include Aki's and Shuey's formulas that are widely used nowadays. ·These new formulas have more definite physical meaning, clearer lithology property,simpler form and easier separation of variates than other's formulas. ·They broaden the application of AVO technique, favour better lithology parameter inversion and advantage separating P wave from S wave. (3)·My AVO filtering concept that copes with the problem existing in seismic horizontal stacking. ·My AVO curve filtering, which is a new processing method for obtaining amplitude fidelity,high resolution and high S/N ratio. ·It is pointed out that traditional CDP stacking concept may be forsaken in more reliable new lithology analysis, which is the development tendency of seismic exploration. The principles and applications of these new methods are illustrated at the conclusion of the article.

本文阐述了如下内容:①提出了平面弹性波反射和透射的统一公式,并阐明了转换波和非转换波动力学特征的差异。指出,“在不同弹性介质分界面上入射平面弹性波,转换波的反射系数和透射系数是射线参数p的奇函数;非转换波的反射系数和透射系数是射线参数p的偶函数”。②作为上述结论的直接应用,本文提出一组以奇偶幂级数形式表示的平面弹性波反射和透射的近似公式,包括目前广泛用于地震勘探的Aki公式和Shuey公式。与前人的公式相比,本文公式具有物理意义明确、岩性关系清晰、形式简洁和易于分离变量等优点。新的近似公式扩展了AVO分析的应用领域、易于实现更为全面的岩性参数反演,并可分离纵波和横波。③针对地震勘探中的水平叠加技术存在的问题,本文提出了AVO滤波的概念,发展了一种振幅保真、高分辨率、高信噪比的处理新方法——AVO曲线拟合滤波,并且指出更为真实的岩性分析方法必须抛弃传统的CDP叠加概念,这是地震勘探的必然趋势。文中最后以实例说明了这些新的处理方法的原理和应用。

AVA inversion methods for lithology parameters mostly are based on the approximation formula of the isotropic theory,and only P-P wave data is used.For the seismic data with large incidence angles,there are large differences between the computation results from AVA isotropic approximation formula and that from AVA anisotropic precise formula.If only P-P wave amplitude is used for lithology parameters inversion,there are some shortages in the respect of the theory basis and the inversion precision.However,inverting the lithology parameter by jointly using P-P wave amplitude and P-SV wave amplitude can increase the additional constraint conditions,and improve the reliability of the inversion results.Taking amplitude characteristic equation of the transversely isotropic media as the theory basis,the paper inverted P wave velocity,S wave velocity,density and anisotropic coefficients with joint multiwave AVA data.The calculation results from the real data indicate that not only the lithology parameters,but also the anisotropic coefficients related to the fractures in the layer can be obtained with this method.The results from the joint inversion method are more stable and reliable than that from P wave data inversion.Therefore,the AVA joint inversion method is an effective inversion method for prestack elastic impedance parameters,the elastic impedance sensitive to the hydrocarbons can be gained with the lithology parameters from the joint inversion,then,oil-and gas-filled,and water-saturated reservoirs can be detected with the gradient changes of the elastic impedance at different incidence angles.

AVA岩性参数反演方法大都是基于各向同性理论的近似公式利用P-P波单分量资料来反演。对于大角度入射的地震资料,基于各向同性理论的AVA近似公式与基于各向异性理论的AVA精确公式的计算结果存在较大差异。仅利用P-P波振幅反演地层岩性参数无论在理论基础还是反演精度上都存在不足,而同时用P-P波和P-SV波振幅联合反演岩性参数,可增加约束条件,提高反演结果的可靠性。以TI介质中的振幅特征方程为理论基础,进行多波AVA联合反演纵、横波速度、地层密度和地层各向异性系数。实际资料计算结果表明,此方法不仅能够可靠的求取地层岩性参数,还能得到与地层裂缝有关的各向异性系数。联合反演结果比单分量反演的结果更稳定可靠,是一种行之有效的叠前弹性阻抗参数反演方法。用反演得到的岩性参数求取对油气反应敏感的弹性阻抗,进而可以利用不同角度弹性阻抗的梯度变化进行油气水的识别。
