| 摘 要： | 叠前弹性波阻抗反演是当前地震反演技术的一个热点,它利用叠前道集为输入,以横波、纵波、密度等测井资料为约束,联合反演出与岩性、含油气性相关的多种弹性参数,进而进行储层物性及含油气性综合判定。其反演结果比叠后声阻抗反演,在可信度方面有很大提高,能够获得更多、更敏感有效的数据,可对含油气性进行半定量和定量描述,具有广泛的应用前景。这里介绍了叠前弹性波阻抗反演技术的基本原理和方法,并对新疆某油田实际资料进行反演分析,其结果为储层预测和储量计算提供了重要依据,获得了良好的应用效果。

| Abstract: | Prestack elastic-impedance inversion is currently a hotspot on seismic inversion technique,which utilizes different offset gathers data and logging data like S-wave,P-wave,density etc,jointly inverts a variety of elastic parameters which is related to lithology and hydrocarbon potential.This inversion method can determine reservoir properties and hydrocarbon potential,and the inversion result has a great improvement in reliability compared with the post-stack acoustic impedance inversion.It can obtain more ... |
