基于结构特征的地震剖面二维可视化方法

针对山地高陡复杂地质构造层位倾角较大，传统的可视化渲染方法破坏了地层的连续性，影响可视化效果。提出一种基于结构特征的地震剖面二维可视化方法。首先，采用邻域加权平均滤波法对地震勘探数据做预处理，提出正切值过滤法进行特征优化选择；其次，采用一种改进的相关算法来提取最具有明显结构特征的序列；最后，以结构特征序列为约束条件，进行二维渲染，输出地震剖面的二维可视化图像。实验结果表明，该方法结构特征明显，具有更好的连续性，提高了可视化的效果。

Research on 2D Visualization Method of Seismic Section Based on Structural Characteristics

In view of the large dip angle of high, steep and complex geological structures in mountainous areas, the traditional visualization rendering method destroys the continuity of the stratum and affects the visualization effect. A two-dimensional visualization method of seismic profile based on structural feature is proposed in this paper. Firstly, the neighborhood weighted average filtering method is used to preprocess the seismic exploration data, and the tangent filtering method is proposed for feature optimization selection, and then an improved correlation algorithm is used to extract the sequence with the most obvious structural characteristics. Finally, taking the structural feature sequence as the constraint condition, the 2D rendering is carried out, and the two-dimensional visual image of seismic section is output. The experimental results show that this method has obvious structural characteristics, better continuity and improved visualization effect.
