Under the condition of thin interbeds with great lateral changes in terrestrial basins, a seismic meme inversion method is established based on the analysis of seismic sedimentology technology. The relationship between seismic waveform and high-frequency well logs is established through dynamic clustering of seismic waveform to improve the vertical and horizontal resolution of inversion results; meanwhile, by constructing the Bayesian inversion framework of different seismic facies, the real facies controlled inversion is realized. The forward model verification results show that the seismic meme inversion can realize precise prediction of 3 m thick thin interbeds, proving the rationality and high precision of the method. The application in the Daqing placanticline shows that the seismic meme inversion could identify 2 m thin interbeds, and the coincidence rates of inversion results and drilling data were more than 80%. The seismic meme inversion method can improve the accuracy of reservoir prediction and provides a useful mean for thin interbeds prediction in terrestrial basins.

在地面盆地夹层薄，横向变化大的条件下，基于地震沉积学技术分析，建立了地震模因反演方法。通过对地震波形进行动态聚类，建立地震波形与高频测井曲线之间的关系，以提高反演结果的垂直和水平分辨率。同时，通过构造不同地震相的贝叶斯反演框架，实现了真实相控反演。正演模型验证结果表明，地震模因反演可以实现对3 m厚薄夹层的精确预测，证明了该方法的合理性和高精度。在大庆长垣中的应用表明，地震模因反演可以识别出2 m的薄夹层，反演结果与钻井数据的符合率均在80％以上。地震模因反演方法可以提高储层预测的准确性，为陆相盆地薄夹层预测提供有用的手段。
