摘　　要：断裂系统精确解释是精确构造和岩性分析的基础。概要介绍了利用地震资料断裂系统解释的多种方法的演变过程和相互联系 ,分析了它们的优缺点 ,阐述了三代相干体、倾角、方位角、方差及混沌等增强不连续的属性计算方法 ,给出了属性计算结果细线化的具体算法与应用实例。最后 。Detailed fracture system analysis lays the foundation for precise structure and stratigraphy description. In this paper several fracture system description methods using seismic data are briefly discussed. Their mutual relation, evolution, advantages and weaknesses are also addressed. The approaches to computing three-generation coherence cubes, to extracting enhancing attributes of discontinuity including dip, azimuth, variance, chaos are summarized. A new graph thinning method adapted from computer vision processing is introduced and illustrated with a real data example. Finally, it is pointed out that the quality of input data is vital to automatic seismic data interpretation comparing to various fracture delineation methods.
