中文摘要：为了获得高精度的地震资料,便于地震资料解释和反演,需要对传统弹性波阻抗反演进行改进,为此,首先概述了弹性波阻抗反演原理及其常见的反演流程,然后简要介绍了弹性波阻抗反演的三类方法(相对波阻抗反演(道积分)、递推反演和基于模型的反演),最后通过3个实例重点论述了弹性波阻抗反演在三种不同介质中的改进及应用。结果表明:弹性波阻抗反演应用于水体介质中,获得的类弹性波阻抗(AEI)可以进一步反演出海水物性参数;弹性波阻抗反演应用于陆地地层中,推导出一种全新的波阻抗(PEI)方程进行波阻抗反演,可直接获得高精度的泊松比;弹性波阻抗反演应用于海底地层中,能够有效地识别出天然气水合物层。应用效果说明,根据不同的实际需求对弹性波阻抗反演方法进行相应的改进,从而能更准确地反演介质的物性参数,更精准地进行地震资料解释,有利于油气资源的勘探开发。

外文摘要：In order to obtain high-precision seismic data and facilitate seismic data interpretation and inversion result,it is necessary to improve the traditional elastic wave impedance inversion.Thus,this paper firstly generalizes the principle of elastic wave impedance inversion and its common inversion process.Secondly,three inversion methods of elastic wave impedance are briefly introduced,relative wave impedance inversion(trace integral),recursive inversion and model-based inversion.Finally,the improvement and application examples of elastic wave impedance inversion in three different media are emphatically discussed through three examples.The result shows that the elastic wave impedance inversion is applied in water medium,and the allied elastic impedance(AEI)can further inverse physical parameters of seawater.Elastic wave impedance inversion is applied in terrestrial strata,and a new wave impedance(PEI)equation is derived to obtain the high precision Poisson's ratio directly.The elastic wave impedance inversion is applied in submarine stratigraphy,which can effectively identify the gas hydrate for the application of elastic wave impedance inversion.The application effect shows that the elastic wave impedance inversion method is improved according to different practical needs,so that the physical parameters of the medium can be more accurately inverted,and the seismic data interpretation can be more accurate,which is conducive and helpful to the exploration and development of oil and gas resources.
