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。

Reservoir characterization can be greatly enhanced by integrating seismic, borehole data and geological information. The theory, method and technique of mutliparameter-constrained inversion is presented in this paper. These are three major parts: well-log inversion (volunetric analysis ), broadband-constrained inversion, and lithology-constrained inversion. The well-log inversion results can not only provide parameters for geological interpretation, but also be used as the initial-model and constrained condition of broadband-constrained inversion. In the broadband-constained inversion, damping-generalized inversion method and optimization method are used to get broadband high-resolution reflection coefficient profile, and broadband acoustic impedance method. The above information is subsequently used to perform lithology-constrained inversion to obtain final lithology-parameter profile, such as porosity profile, to be compared with well-log curve, layer effective pressure profile, etc.

文章论述了包括测井反演、宽带约束反演和岩性约束反演在内的多参数约束反演的理论。其中测井反演不仅提供用于地质解释的参数,还把它作为宽带约束反演的初始模型及约束条件;宽带约束反演利用阻尼广义道方法和最优化计算方法,提供宽频带的高分辨反射系数剖面,最终获得宽带波阻抗模型。利用以上资料,进行岩性约束反演,可得到与井对比的孔隙度等岩性参数剖面,最终获得过井储集层地质剖面。
