Based on the theory of seismic curvature attributes, this paper analyzed features of seismic curvature attributes and found out effective seismic curvature attributes to interpret the seismic data. Suming up the application of the eismic curvature attributes and the notable problems during the process of application,2D curvature attributes explicit physical meanings and obvious advantages in identification of structure characteristics. The attributes are usually related to seismic horizon's geometric shapes(like dip, azimuth and curvature, etc.),which are effective to describe geologic configuration, hierarchy and fault system. Minor faults on general seismic section show the features such as even tiny variety, twist, weaking abruptly of the amplitude.These tiny varieties show small linear structure on curvature attribute of the seismic horizon,so minor faults can be interpreted according to linear structure abnormity. The length of abnormity and directions represent the continued length and directions of faults respectively. The applications show that it is effective and convenient to interpret faults using seismic curvature attributes. The track of the faults and the sizes, shapes and boundaries of sedimentary bodies become continuous and clear. And it is beneficial for fault interpretation.
