【摘要】 叠前反演以其多信息性和良好的保真性在岩性油气藏的勘探与开发中占据着越来越重要的地位。本文讨论了叠前AVA地震参数反演的方法,有P波单分量反演、S波单分量反演及PP波PS波联合反演。以振幅特征方程为基础对单个CMP点地震记录用这三种方法进行反演,得到此CMP点目的层段内的纵横波速度、密度等岩性参数,并对比分析了各种方法的精度。更多还原

【Abstract】 Pre-stack inversion plays an increasingly important role in the litho logic reservoirs’ exploration and development for its multi-information and good fidelity.This thesis discussed pre-stack AVA seismic parameter inversion method based on the waveform,including PP inversion,PS inversion and joint PP and PS seismic inversion.Based on Zoeppritz equation of VTI media,inverse the seismic record of a CMP in three ways exclusively.Thus we get the some parameters,such as P-wave velocity,S-wave velocity,density and so on.更多还原
