摘　　要：针对生物礁储层内部弱地震响应特征的地震解释,提出了一种利用波动方程正演优选地震属性达到对礁体内部复杂结构精细刻画的解释技术。该技术以频率-波数域数值模拟方法为手段,充分考虑地震解释多解性中多个解所对应的地质模型并对其进行数值模拟,对模拟出来的正演结果进行波场特征和反射机制分析,指导地震属性方法的选择,从而确定多解性中的唯一解,最终得到地质体的精细解释。For the seismic interpretation of weak seismic response characteristics in organic reef reservoir, this arti- cle puts forward an interpretation technique which makes use of wave equation forward modeling to optimize seismic parameters so that they can finely depict the interior structure of reefs. This technique uses frequency - wavenumber domain numerical simulation and the geological models corresponding to each solution in multiplicity of seismic in- terpretation to perform numerical simulation. Then, performing wave field characteristic and reflection mechanism analysis of the result of forward modeling, which guides the selection of seismic parameters and determines the u- nique solution in multiplicity, and finally acquires the finely interpretation of geologic body.
