Abstract: The uniformity of 3D geometry is essential to seismic acquisition in the spatial continuity, balance, as well as follow-up data processing (prestack migration) and comprehensive explanation. In this paper, the analytical evaluation method of 3D geometry is presented to be applied, through analyzing and evaluating the uniformity of 3D geometry on fold, offset, azimuth and offset-fold qualitatively or quantitatively, so as to comparatively analyze the sampling uniformity difference of 3D geometries on the whole, then feed back the analysis results to design process of 3D geometry, make the choice of 3-D geometry more scientific and reasonable

Key words: 3D geometry, fold, offset, azimuth, offset-fold, uniformity, non-uniform coefficient
