浅谈弹性波阻抗反演技术

【摘要】 弹性波阻抗反演技术是结合了常规声阻抗反演和叠前AVO反演的地震反演技术,利用不同入射角的地震叠加数据进行波阻抗反演的。本文对弹性波阻抗反演技术的基本原理,优缺点、应用条件以及应用实例进行了简单的介绍。通过应用举例说明了该技术在识别油气层,描述储层以及提高岩性和流体的预测能力方面都是一种有效方法。更多还原

【Abstract】 Elastic wave Impedance inversion technique is the seismic inversion technique which combines the conventional acoustic impedance inversion and the prestack.AVO inversion.And the technique makes use of the seismic stack data of different angle of incidence.This article simply introduces the fundamental principle,merit,demerit,applied condition and and application of elastic wave Impedance inversion technique.It is illuminated that the technique is a effective method in identifying hydrocarbon reservoir,describing reservoir and improving predictive ability of lithology and fluid by giving examples.更多还原
