Abstract: This paper tries to make a quantitative evaluation of the 3D seismic geometry attributes and particularly takes into account the vertical and horizontal uniformity. From an angle of creation, it comes up with the concepts of the geometry’s uniform factors, new aspect ratio, effective folds and formula for expression of relations and points out the geophysical significance of these new concepts. The uniform factors, new aspect ratio and effective folds are used, together with the maximum offset, to establish an overall quantitative evaluation method of the geometry attributes on the basis of their contributions to the geometry, and offer a numerical example. The results of the numerical example indicate that the mathematical formula of the overall quantitative evaluation covering uniform factors, azimuth, amount of folds and maximum offset can be used to directly calculate the attributes of different geometries and the assessed values of the attributes in the future design of 3D geometry. This method is simple, fast and effective.
