英文摘要：

Based on the application of the curvature attribute of two-dimensional Gaussian iterated smoothing filterings, we can realize the effective identification of geological structures,such as fissure, faults, bends and folds. This article describes the basic theory of the curvature attribute, analyzes the limitations of using no filtering and after median filtering, Gaussian filtering dealing with real information, proposes a method of using two-dimensional Gaussian iterated smoothing filtering to express the curvature attribute. It deals the original data volume with the median filtering and two-dimensional Gaussian iterated smoothing filtering, calculates the curvature attribute from the processed seismic data. Then it compares the effects of seismic attribute mapping through a variety of filtering and analysis of the similarities and differences. We have concluded that it has a good application effect for high-resolution structure and fine identification, especially in the discrimination of buried faults and cracks and description of geometric features.
