弹性阻抗反演及影响因素分析—基于connolly公式

The inversion of flexible impedance and the factors influence on it— base on the connolly formula

与传统的波阻抗反演相比,弹性阻抗反演具有信息丰富、分辨率高的特点;与定性的AVO反演相比,该方法达到了定量的程度,而且计算速度快。依据connolly公式计算的弹性阻抗受到多重因素的影响,其中V s/V p和角度取值的选择会对反演的结果造成很大的影响。本文就是基于connolly公式,再结合实际资料及V s/V p和角度θ的取值对计算的弹性阻抗(E I)的影响展开讨论的。

Compare with traditional inversion ol wave impedance, the inversion ol flexible impedance have these characteristics, abundant imformation and high resolution ; Besides, compare with qualitative AVO inversion, this method attain quantitative degree, and computed quickly . The flexible impedance that computed by the Connolly formula affected by multiaspect. Among them , take the choice of the value of Vs/Vp and the angle will aspect the inversion results sharply. This article sets out to combine actual data the Vs/Vp and the angle from the connolly formula to take influence upon calculating flexible impedance （EI） to Carry on a discussion.
