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

Compare with traditional inversion of wave impedance,the inversion of 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.
