摘　　要：本文以高分辨率地震数据为基础,由伽马曲线生成拟声波曲线的方法做了波阻抗反演,反演结果能正确的揭示丰谷构造砂岩的横向展布。在砂岩的横向对比时,很好的利用了波阻抗数据得到的砂岩横向展布并结合纵向上的测井岩性识别及油气解释成果,能较好的得到含油气储层的分布特征。This article takes the high-resolution seismic data as a foundation, with the production ot quasi -acoustic from gamma ray well log, we made an acoustic impedance inversion; the result of inversion can correctly reveal the horizontal distribution of the sandstone. At last, we made sandstone correlation by synthesizing the inversion result and well log interpretation, and better obtained the oil gas reservoir distributed characteristic.
