中文摘要：

地震资料解释几乎覆盖整个基础地质的研究过程,而其中三维地质目标体的表面重建及可视化又是极其重要的一部分。在实际的地震解释过程中,不同的地震属性从不同的方面反映出地震数据的特点,为了结合不同的地震属性更加全面的反映地质目标体的特点并且消除单一地震属性数据带来的多解性问题,提出一种新的三维地质目标体表面重建及数据填充和表面平滑的方法流程。介绍基于模糊逻辑的多属性数据特征融合的地质目标体提取方法;介绍基于形态学方法的地质目标体数据填充方法和基于高斯平滑算法的地质目标体表面平滑。通过对实际地震工区进行仿真实验,得到理想的实验结果,为三维地质目标体表面重建提供一种新的研究思路。

英文摘要：

Almost all of the basic geological study and petroleum geology study will involve the seismic data interpretation, and 3D surface recon-struction and visualization of anomaly bodies is an important part of seismic data interpretation. In the practical seismic data, different seismic attributes often reflect different aspects of underground situation. In order to combine different seismic attributes to reflect the characteristics of target body more fully and eliminate the uncertainty of a single seismic data, proposes a new surface reconstruction method work flow of 3D target body. This workflow includes surface reconstruction method, data filling and surface smoothing. Introduces the method of 3D geological target body extraction based on data fusion of different seismic attributes, and this method adapts the method of fuzzy logic. Introduces data filling of 3D geological target body method based on morphology and surface smoothing of 3D geological target body based on Gaussian smoothing. This new workflow is used in practical project of geological interpretation, and has some nice results. It gives surface reconstruction of 3D geological body a new research thought.
