摘　　要：作者在文中对深度 30 0 0 m以下的砂、泥岩互层透镜体地质模型及其等效厚度的单砂透镜体模型进行了正演模拟 ,并分别对其进行了道积分反演、均方根振幅分析和频谱分析。通过对比分析 ,得出了一些新的认识 ,它对砂、泥岩薄互层地震反射特征研究 ,特别是薄储层预测具有现实的指导意义。In this paper, the authors describe a new method for forward modeling to thin sand-mud interbed and pure sand lens under the depth of 3000m. Then by analyzing the modeling results of the two models from calculating integrated trace, mean squared root amplitude and spectrum, We have a new understanding to the formation with thin sand-mud interbed, which is very significant for studying seismic reflection characteristic of thin sand-mud interbed, especially in thin reservoir prediction.
