研究区受多期次构造活动控制，走滑断层、微小断层发育，断层倾角陡立、断距小，使得常规解释技术不能满足要求。介绍了多属性断层解释方法，包括沿层面属性：倾角方位角、曲率、边缘检测，体属性：相干体、蚂蚁体的算法原理及敏感参数。比较各属性，优选出相干+曲率+蚂蚁体的最佳属性组合，检测断层平面分布。结合剖面响应进行走滑及微小断层解释及闭合，利用三维立体显示，对断层合理性及展布进行评价；实现对工区断层的合理有效解释。

The study area was controlled by multi period tectonic activities,strike slip、minor、high steep、short displace-ment faults are development. so the conventional interpretation techniques do not meet the requirements. This paper re-search about multiple attribute for fault interpretation: introduces the kinds of methods, including along the level attri-bute、dip and azimuth、curvature、edge detection、3D attribute、the algorithm principle and the sensitive parameters of co-herent and ant body.Compared each attribute,I figure out three points:1、the combination of coherency+curvature+ant body is the most useful for detecting fault distribution; 2、combining plane attribute and seismic profiles to make sure fault closed;3、using 3D viewer, to evaluate the rationality and the distribution of faults;and finally realize the reason-able and effective fault explanation.
